I can't seem to get any version of this mod to work in my private mod assortment. I was hoping the log file would help identify what I am doing wrong.

Thanks in advance.

You need to update Fabric API. Battle Towers uses some newly released FAPI functionality for adding structures to biomes. This release should work.

That version did work. Now I can play one my favorite mods again, thanks!
