Minecraft v1.16.5
Forge v36.1.24
More Waterlogging v1.5
Statement v4.0.1

After installing I seem to be getting a mixin crash, although I'm unsure which other mod it is conflicting with.
Crash Report

Not my fault, one of the mods installed has a conflicting mixin/js coremod

If you find it, post it here so that others know.

This crash only happens when More Waterlogging is added to my modpack. If I remove it, the modpack works perfectly.

It's because more waterlogging or statement has a mixin that conflicts with another one, but that doesn't mean that more waterlogging is to blame.
There is nothing I can do on my end until the conflicting mod is at least identified.

Ok, yeah, looks like the crash is triggered by Statement and that there is also an incompatibility with FerriteCore.
Virtuoel/Statement#5

Closing as resolved since it doesn't involve this mod
