I was making an iron farm and I named a zombie to keep it from despawning. However, for some reason, it keeps going invisible to me. Some of my villagers do that as well.
I still hear the mobs that are invisible, the zombie deals damage to me when I'm close but I can't see him nor my other villagers. When I log out and re-login I see them until I move away from the chunks then they are invisible but I still hear them and stuff, can someone help?
Is it because I started the world on 1.16.1 and then changed to 1.16.4?
