Basically all pigs, cows and sheeps in the game are invisible. They've recently added custom CEM features, that for some reason are not working. I can't say for sure it's a EMF problem, but I just want to warn about the issue just in case, since the last Alacrity update specifically added custom animals with CEM.

Minecraft is working in 1.20.1 with the latest EMF, EMT and Entity culling versions.
