How to Fix “World Cache Version Mismatch” on Your Rust Server

If you’re seeing the error “World cache version mismatch” or “World File Outdated” on your Rust server, it means there is a conflict between your server’s map version and the expected version. This issue usually occurs after a Rust update, when using outdated map files, or due to incorrect configurations.

Follow this guide to resolve the issue and get your server running again.

Step 1: Delete the World Cache

1. Connect to your server via SFTP or File Manager.
2. Navigate to your Rust server directory:

   /server/<your_server_identity>/
   

3. Locate and delete the outdated world files:
   • *.sav files (e.g., rustmapv1.sav, proceduralmap.sav)
   • *.map files if applicable
4. Restart your server to allow Rust to regenerate the world.

Step 2: Ensure Your Server is Updated

Your Rust server must be running the latest version. To update your server:

1. Go to configuration tab, find the Update Server button and click it.
2. On console click restart to start an update process.
3. Once updated, restart your server.

Step 3: Verify Custom Maps (If Applicable)

If you’re using a custom map, it may be outdated. Try these steps:

1. Download the latest version of the custom map from the provider.
2. Replace the old .map file in your Rust server directory.
3. Restart your server and check if the issue is resolved.

Step 4: Force a Map Wipe (If Needed)

If none of the above steps work, you may need to wipe the map:

1. Delete all world-related files from /server/<your_server_identity>/.
2. Change your map seed or map size in the startup settings.
3. Restart the server to generate a fresh map.

Conclusion

By following these steps, you should be able to resolve the “World Cache Version Mismatch” error and get your Rust server back online. If you continue to have issues, consider checking Rust’s latest patch notes or contacting support.
