I was curious to see what this mod was like in my pack but then bad mixin things happened and I figured you'd wanna know so you can improve mod compat.
Here is the log: https://gist.github.com/mxnmnm/404f8904e13133dec8328cc9997df224

Well, this is unlikely to be ever fixed as my attention is completely shifted towards 1.16-1.18 now

But thanks anyway!

fyi the exact crash in the log you've sent is caused by incompatibility with betterhurttimer mod, whatever it is
