How Auto‑Update Plugins & Mod Sync Works

Table of Contents

Introduction

Keeping plugins updated and maintaining synchronized mod sync lists across multiple players is one of the more complex aspects of managing a modded game setup. Whether you are running a solo setup that needs to stay current with frequent plugin releases or coordinating a multiplayer session where every participant must run identical mods.

Understanding how auto update and mod sync actually function prevents the frustration of version mismatches and broken sessions.

R2modmanager and the broader Thunderstore ecosystem provide several tools that address both needs, but neither process is fully automatic in the way many players initially expect. Knowing exactly what is and is not handled automatically allows you to build a workflow that keeps everything current with minimal manual effort.

Quick Facts about How Auto‑Update Plugins & Mod Sync Works

No mod manager currently offers true background auto update that applies plugin updates without any user interaction
R2modman checks for available plugin updates when opened and displays update indicators in the Installed tab without applying them automatically
The Update all button within a profile provides the closest equivalent to one click bulk updating for all installed plugins simultaneously
Mod sync between players is achieved through r2modman’s profile export and import system rather than a live synchronization connection
A shared profile code or file ensures every player in a multiplayer session installs identical mod versions from the same Thunderstore source
BepInEx updates follow the same update notification and manual application process as regular plugins
Plugin updates that introduce breaking changes or new dependencies require manual review before bulk applying to avoid session disrupting crashes
Thunderstore’s modpack system provides an alternative sync method where a single modpack listing keeps an entire group’s mod list updated through a shared package reference
Automatic update awareness can be supplemented through external tools such as mod author GitHub watches and community Discord channels that announce plugin releases

What Is the Difference Between Auto Update and Mod Sync?

Auto update and mod sync are related but distinct concepts that solve different problems in a modded game workflow. Conflating them leads to expecting functionality from each system that the other actually provides.

Auto update addresses keeping your own installed plugins current with the latest releases from Thunderstore. Mod sync addresses ensuring that multiple players in a shared session are all running identical plugin versions regardless of when or how they each manage their individual setups.

How Auto Update Functions in Practice

Auto update in the context of r2modmanager and Thunderstore based mod management means the application checks for newer versions of installed plugins when it connects to Thunderstore and surfaces those available updates in the interface for the player to apply.

This is notification based updating rather than background silent updating. The player must open r2modman and take an action to apply available updates. The update check itself is automatic but the application of updates requires deliberate player input.

The auto update sequence step by step:

R2modman launches and connects to the Thunderstore API
The application compares the version numbers of all installed plugins against the current versions listed on Thunderstore
Any plugins with newer available versions are flagged with update indicators in the Installed tab
The player opens the Installed tab and sees which plugins have available updates
Updates are applied either individually per plugin or through the bulk Update all action
R2modman downloads the new plugin versions and replaces the installed files within the active profile
The game is launched after updates complete to confirm the updated plugins load correctly

What auto update does not do:

It does not apply updates without the player opening r2modmanager and navigating to the Installed tab
It does not update plugins across all profiles simultaneously; each profile must be updated independently
It does not evaluate compatibility between a new plugin version and other installed plugins before applying
It does not revert updates automatically if a new version introduces breaking changes

How Mod Sync Functions in Practice

Mod sync in r2modman is achieved through the profile export and import system. There is no live real time synchronization connection between players. Instead, one player exports their profile configuration as a shareable code or file and other players import it to replicate the exact mod list and versions.

This is a point in time snapshot approach rather than a continuous synchronization system.

The mod sync sequence for multiplayer sessions:

One player in the group designates their profile as the reference configuration
That player exports their profile through r2modman’s profile export feature
The export produces either a shareable code string or a downloadable profile file
Other players import the code or file through r2modman’s profile import feature
R2modman downloads all plugins listed in the imported profile at the exact versions specified
All players now have identical plugin installations from the same Thunderstore sources
Before each subsequent session, the reference player re exports if any updates have been applied and shares the new export with the group

What mod sync does not do:

It does not create a persistent live connection between players that automatically propagates updates
It does not notify other players when the reference player updates their plugins
It does not prevent individual players from independently updating plugins after the initial sync
It does not resolve conflicts if players have additional plugins installed outside the shared profile

How to Set Up Efficient Auto Update Management

Since plugin updates require manual application through r2modman, building an efficient update routine reduces the effort involved in keeping plugins current without requiring daily manual checks.

Configuring R2ModManPlus for Update Awareness

R2modman’s update checking is automatic every time the application connects to Thunderstore on launch. No additional configuration is needed to enable update detection. The practical optimization is in how you respond to update indicators when they appear.

Building an efficient update response workflow:

Open r2modman before every play session and allow it to fully connect to Thunderstore before navigating to the Installed tab
Review update indicators in the Installed tab and check the Thunderstore pages of major plugins showing updates before bulk applying
Apply updates individually for critical framework plugins such as BepInEx to review change notes before updating the full list
Use the Update all button for minor plugin updates from well maintained mods with consistent release quality
After applying updates, launch the game through Start modded and monitor the BepInEx log for any errors introduced by the updated versions before committing to a full play session
If an update introduces errors, identify the problematic plugin through the log and revert to the previous version by uninstalling and reinstalling the specific version from Thunderstore’s version history

Handling Plugin Updates That Introduce New Dependencies

Some plugin updates add new dependencies that must be installed alongside the updated plugin for it to function correctly. R2modman handles this automatically during the update process by resolving and installing new dependencies as part of the update action.

What to expect when a plugin update adds new dependencies:

R2modman presents a dependency list before completing the update showing any new requirements
New dependencies are downloaded and installed automatically alongside the updated plugin
The new dependencies appear in the Installed tab after the update completes
Existing plugins that share the new dependency benefit from it being present without any additional action
If the new dependency conflicts with an existing plugin, r2modman may display a warning before completing the update

Common Problems and Solutions:

Problem: Update all applies a plugin update that crashes the game on the next launch Solution: Open the BepInEx log to identify the problematic updated plugin, disable it in the Installed tab, and check its Thunderstore page for known issues with the latest release before re enabling
Problem: A plugin shows an available update but clicking update produces a download error Solution: The Thunderstore CDN may be experiencing temporary issues; close and reopen r2modman to retry the update after a fresh Thunderstore connection is established
Problem: After updating all plugins the game launches correctly but some features from specific plugins are missing Solution: A silent update may have changed or removed specific features; read the update change notes on the affected plugin’s Thunderstore page to confirm whether the missing feature was intentionally altered
Problem: R2modman shows no available updates despite knowing a plugin released a new version recently Solution: R2modman may be displaying cached version data; close and reopen the application to force a fresh Thunderstore catalog check before concluding no updates are available
Problem: Updating a plugin in one profile does not update the same plugin in other profiles Solution: This is expected behavior as each profile maintains independent plugin installations; navigate to each profile separately and apply updates within each one to keep all profiles current

How to Sync Mods Between Players Using R2ModManPlus

Achieving a synchronized mod setup across a multiplayer group requires one player to act as the configuration reference and distribute the profile to other participants before each session. This process is straightforward once the workflow is established but requires coordination between players.

Exporting a Profile for Group Sync

The profile export feature in r2modman generates a shareable representation of the active profile’s complete plugin list including exact version numbers for every installed plugin. This export can be shared through any communication channel the group uses including Discord, a group chat, or a shared document.

Step by step profile export for group sync:

Open r2modman and navigate to the profile you want to share with your group
Confirm the profile contains exactly the plugins you want all players to run including correct versions
Look for the Export profile option in the profile selector menu or the profile tools section
Choose between exporting as a shareable code string or as a downloadable profile file depending on what your group prefers
Copy the code string or save the profile file to a location you can share from
Share the code or file with all players in your group through your preferred communication channel
Instruct players to import the profile before the next session using r2modman’s import feature

Importing a Shared Profile for Sync

Players receiving a shared profile code or file import it through r2modman’s profile import feature. The import process downloads all listed plugins at the exact specified versions, creating an identical setup to the reference player’s profile.

Step by step profile import for group sync:

Open r2modman and access the profile selector
Look for the Import profile option within the profile management section
Choose whether to import from a code string or from a profile file depending on what was shared
Paste the code string or select the downloaded profile file to begin the import
R2modman displays the complete plugin list that will be installed as part of the import
Review the list to confirm it matches the expected shared configuration before confirming
Allow r2modman to download and install all listed plugins at the specified versions
Confirm the imported profile appears in the profile selector with all plugins listed in the Installed tab
Launch the game through Start modded to verify all imported plugins load correctly before the group session

Using Thunderstore Modpacks for Persistent Group Sync

Thunderstore modpacks provide an alternative sync approach that is particularly useful for groups that play together regularly and want a persistent shareable mod list that updates through a single reference point.

A modpack is a Thunderstore package that lists a curated set of plugins as dependencies. Installing the modpack through r2modman installs all listed plugins automatically. When the modpack is updated by its creator, players update the modpack through their normal update workflow and r2modman applies all associated plugin updates simultaneously.

How to use Thunderstore modpacks for group sync:

One player in the group creates a Thunderstore modpack listing all agreed upon plugins as dependencies
The modpack creator publishes it to Thunderstore as either a public or unlisted package
All group members search for and install the modpack through r2modman’s Online tab
When plugins need to be added or updated for the group, the modpack creator updates the package on Thunderstore
Group members update the modpack through r2modman’s standard update process which cascades updates to all listed plugin dependencies
This approach reduces ongoing sync coordination to a single modpack update notification rather than profile re export and redistribution

Frequently Asked Questions

Does r2modman update plugins automatically without me opening it?

No. R2modman does not run background processes that apply plugin updates silently. Update checking occurs when you open the application and connect to Thunderstore. Applying available updates requires navigating to the Installed tab and initiating the update process manually.

What is the fastest way to keep all plugins updated?

Open r2modman before each play session and use the Update all button in the Installed tab to apply all available updates simultaneously. This approach takes under a minute for most plugin lists and ensures you are always running current versions before launching the game.

How do I sync mods with friends for multiplayer?

Use r2modman’s profile export feature to generate a shareable code or file representing your complete plugin list. Share this with your group through Discord or another channel and have each player import it through r2modman’s profile import feature before the session.

Do all players need the same r2modman version for mod sync to work?

Profile import and export compatibility between different r2modman versions is generally maintained but not guaranteed across very large version gaps. All players using a recent current version of r2modman eliminates any compatibility concerns with the profile format.

What happens if one player in a group updates plugins but others do not?

Version mismatches between players in a multiplayer session can cause desync issues, missing content, or session instability depending on which plugins differ. Re exporting and redistributing the reference profile after any updates ensures all players return to an identical configuration before the next session.

Can I automate mod sync for a regular group without manual re export each time?

Yes through Thunderstore modpacks. Publishing your group’s agreed mod list as a Thunderstore modpack allows all players to update through the standard r2modman update process when the modpack is revised, eliminating the need for manual profile re export and redistribution after each update cycle.

Why do some plugins not show update indicators even after new versions are released?

R2modman may be displaying cached Thunderstore catalog data from a previous session. Close and reopen the application to force a fresh connection and catalog check. If the update indicator still does not appear after reconnecting, verify the new version is published on the plugin’s Thunderstore listing directly.

Is mod sync the same as co op multiplayer mod compatibility?

No. Mod sync ensures all players have identical plugin installations. Co op compatibility is a separate consideration determined by whether each individual plugin supports multiplayer play. Syncing mod lists is a necessary prerequisite for multiplayer modding but does not guarantee every synced plugin functions correctly in a co op session.
