How to Downgrade your tModLoader Server to Version 1.3

Downgrading your tModLoader allows you to run mods that have not been updated to the latest version 1.4.

Important: If you have upgraded your current world to version 1.4 you will not be able to use this on your legacy 1.3 server, therefore you will have to generate a new world.

Downgrading tModLoader

This can easily be completed with the use of Steam Betas.

  1. Access your control panel and Stop your server.
  2. Set your Server Type to tModLoader.
  3. Start your server to generate the tModLoader config files.
  4. Once the server has fully booted, Stop your server.
  5. Navigate to Files > Config Files.
  6. Open Terraria Server Settings.
  7. Set steam_beta to 1.3-legacy.
  8. Set World Name to a new name, this will allow the server to generate a 1.3 world.
  9. Save and Start your server.
