Reset options

Because the pack is using Config Manager or YOSBR, your vanilla options and most of the mod ones will not change when you upgrade. This is done so that you can upgrade without having to reconfigure your options all the time.

However, at some point you may still want to do that in order to get the latest changes.

Modern versions

1. Launch the game

2. Go to Mods -> Config Manager -> 🎛️

3. If you want to apply latest changes but keep configs for added mods, select Update modpack's configs.

   • If you want to delete all configs and start fresh, select Reset modpack's configs.

4. Close the game and start it again. See if it works.

   • If you got an error (especially on alpha or beta versions), start the game again to ensure configurations are properly applied.
