Note that net/minecraft/class_1132 is IntegratedServer.

I believe this bit is the problem: https://github.com/Tigereye504/chestcavity/blob/master/src/main/java/net/tigereye/chestcavity/mixin/MixinLivingEntity.java#L321-L323. OrganUtil then imports IntegratedServer, and doesn't appear to use it? So I'm confused why this is causing an exeption, but thats where I am with debugging so far.

I'll write a fix in the next couple days if I have some time. If someone's reading this and wants to have a go at fixing it, be my guest :)
