I think it may reproduce with below 1.6.4 protocol

Will take a look at this when I have time

does this issue happen only with the specific protocol?

I've tried multiple times but I don't think I can reproduce it anymore

Hmm was probably an issue with ViaFabricPlus then. I can't find anything related to my mod in your crash log file anywhere. My mod shouldn't really affect other mods as it's just a simple mixin with no practical point of failure. I'll mark this issue as closed now, reopen it if you can get it to work again.
