With version 1.1.3 installed, the game crashes when I open the config of any mod from mod menu. 1.1.2 works fine. I think something might be wrong with the auto config/cloth config setup.

Hm, I'm not sure what could be causing this. Maybe a conflict with optifabric or Slight GUI modifications. Works fine for me, so it has to be a mod conflict

Sorry, turns out one of my mods was outdated and updating it fixed the problem.
