When this mod is installed it causes a crash when a player has the CyclonicCleaveEffect from SimplySkills applied. (Gained by casting the Ascendency ability CyclonicCleave)

Removing this mod makes the issue go away.

couldnt reproduce it, but added more safety checks to 3.1

I can't seem to reproduce it either in a minimal environment and all mods updated. Crossing my fingers that updating the mods in my modpack will do the trick. Thanks for your time.
