I can't be a werepyre for some reason. When I start a new world, curse my self with susceptibility, got a totem of undying, and then nearly died from werepyre while holding totem of undying.

The game crashed whilst ticking entity
Error: java.lang.ClassCastException: de.aelpecyem.besmirchment.common.entity.WerepyreEntity cannot be cast to net.minecraft.class_1657
Exit Code: -1
