How To Set The Mod Version On Your Open World RimWorld Server

An Open World server only lets in players whose Open World mod reports the same version as the server's Mod Version setting. New servers start on 1.3. Here's how to change it.

Changing the Mod Version

  1. 1
    Log in to Bropanel and select your server.
  2. 2
    In the sidebar, go to Settings.
  3. 3
    Under Basic, edit Mod Version and enter the version your players' Open World mod reports, for example 1.3.
  4. 4
    Click Save & Restart to apply your changes.

When a player with another version tries to join, your server console shows a line like Player Tried to join with version 1.3 of the mod when server is on player version 1.2. Set Mod Version to the first version in that line.
