[MC-216109] Sometimes I get invisible zombies or drowned spawning and I can't even attack them

It interrupted me when I was making an iron farm plus they aren't stopped by rails like normal zombies. I haven't tested it in 21w07a, so I'm not sure if it's in their but it's defiantly in 1.16.5. It only happened when I was building my iron farm for some reason.

can you add steps to reproduce the issue, so It can be tested?

Were you using Optifine when this occured?

Yes I was using optifine.

I gave a zombie a carrot put it in a chamber with villagers, then it went invisible in a bit, then I could see it again, and it just keeps doing that.

This is due to Optifine. See MC-193509. This can be fixed by updating Optifine, but remember that Optifine invalidates any report as it is not made by Mojang and is a mod
