So I had air bending and I was using the air blade move the last version dragon claw I hit one of the creatures from the other mod the undead swine then I crashed it doesn't happen to any other mob from what I know of also I sent the same issue to the author of the other mod because I dont know which mod is causing it and here's the crash report

edit:so it seems like any of the air bending move crash when interacting with the undead swine I will test if other bending crash with the mob

edit 2:so after experimenting and many crashes it seems like most abilities crash when interact with the mob but not all of the abilities

That's an issue on their side, but I'll still look into it.
