Starting the game with Alex's Caves installed crashes the game due to mixin conflicts with this mod.

Create a issue in Alex's Caves repository.
We went through something similar a year ago, but then there was a conflict with citadel...

A terrible fix was made on Alex's side, anyway, all I can say is this: Don't play with Alex's caves...
