Hope you still support on this version, crash happen with 0.11.2
Log here

Seem like Mixin incompatibility

Have you tried running the mod alone without all of the other mods?

Crashed wile opening it up in 1.12.2

The game crashed whilst there was a severe problem during mod loading that has caused the game to fail
Error: net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from Controllable (controllable)
Exit Code: -1

The same thing happend with me so I started using 1.18.2, but my switch pro controller won't do anything even though it says it's connected

Closing this issue as I no longer maintain the 1.12.2 version of this mod
