I figured that I would report a crash.
I was putting weapons on the new battleship in this mod and when I went to auto assign weapon groups, the game crashed.
I noticed that you released a new version with some bug fixes, tried again, and experienced the same crash.
I don't know if this helps you, but this is the crash log from my game:
