Rendering layers are completely bugged in some areas, as shown in the pics, mobs in the front appear behind all others and the ones in back appear up front, and the face appears to be behind the player's head
most of the pics are from me and two are from my friend, so its not only an issue for me
The affectd area is the chunks around chunk 15 4 17 (xyz 240, 64, 272), and there is an invisible spider living there if that has any relevance, but i think it started before we started keeping it as a pet
