I'm making a mod that uses mixin injection to nerf boats being super fast over ice.

Does this mod define a similar class that wouldn't be effected by an injection to BoatEntity, or does your boat extend it?

I tested my mod with yours and it didn't work, so I'm inclined to assume the former.

Do you know of some work around for this?

I actually found the file in Abnormals Core. I post it there.

Our boats in AC don't override anything to do with faster motion over ice, so mixing into boats will work properly on our boats too.
