Hello.

I'm not sure why this happened but back when I first tried out Alex's Caves, the following mods for whatever reason weren't compatible with it and caused it to crash:

-Recrafted Creatures

-Biome Makeover

-Biome Backlogs

I don't know if this is still the case or what happened with it, but either way, I'd like to have this issue looked into/looked at and considered in the future. Hope this helps.

(Edit: Nevermind. Apparently this issue was fixed long ago. Sorry.)
