Whenever I jump attack a mob, the game immediately crashes. Crash log says

java.lang.NoSuchMethodError: mythicbotany.alftools.AlfsteelHelm.onCritDamageCalc(FLnet/minecraft/entity/player/PlayerEntity;)F

This happens despite nothing related to the mod loaded (no armor, tools, anything on self or mobs)

Which version of botania are you using? If you're anything below 1.16.4-411, please test it with said version and let me know if that fixes the issue.

I was using 1.16.4-410; updating seems to have fixed it. Thank you!
