Hello there!
There is an issue (I think) with how FanProcessingType class works when this mod is installed

My Mixin is: https://github.com/Kryeit/Missions/blob/1.18/common/src/main/java/com/kryeit/mixin/create/FanProcessingMixin.java

I was trying to bring compat to this mod, but it crashes on startup without modifying the mixin.

Solved this, it was an issue on my end!
