Hi! First thank you for the mod.
I encountered this bug with the following error message:

Exception ticking hediff (LuciferiumHigh ticksSinceCreation=10469) for pawn AA_BlizzariskClutchMother51609. Removing hediff... Exception: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

I did some testing and it works fine on pawns and other vanilla/AA animals. So I think it's something to do with this mod:https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2861530452

Thank you!
