All types of mobs/entities keep disappearing. I thought it would go away with the new fix but it kind of got worse. I saw some people complain about some disappearing, but usually it's one or two entities and a but at a time. I have an artificial village and had over 30 villagers and then all but 2 disappeared in one go along with 2 golems. I put tropical fish into an artificial tropical lake and 25 out the 30 fishes disappeared. Most of my chickens disappeared and finally, all of my bees disappeared at once. Not even most of the bees disappeared but all of them at once. After the last update (1.16.40 hotfix) it actually got worse. Every single time I play there are villagers missing, sometimes they even disappear while I'm playing and I'm away from the village. This is all just from one world. They didn't get killed because my world is on peaceful and my village is super safe, so they didn't die.
