So far seen Piglins, Skeletons, Drowned going invisible untill i exit to main menu and re-enter. It happens in 1.16.4 release and in 1.16.3 aswell (as i tried to downgrade to the version that supposedly 'fixed' this) Turning off dynamic lights doesn't fix it. Having it off fixes the issue (apparently) but i am not sure i'll do a playthrough with it off and i will report if i notice invisible mobs again. I'll update this if I get any more concrete information.Īs i read more and more through older posts about this issue i think it might be related to Dynamic Lighting setting. (Note: I have not yet changed dimensions on this world. Now that I've chased it down and befriended it, it doesn't seem to be disappearing anymore.

I'm not sure what did it because I didn't know exactly where they were because they were running from me (I could hear them), but I disabled a few of the optimization settings before the first one reappeared.

Also, there were a couple of cats in a village that were invisible for the longest time, which I eventually got to reappear somehow.

Ran into an illager squad and only 2 of them were visible, at least one more was invisible (I ran from it and eventually ran into a creeper that exploded and killed it, lol).
