In my Minecraft PS4 1.16 world, constantly now villagers or mobs I have nametagged, leashed, fed or bred have despawned. This has happened with foxes, turtles, villagers, dolphins, fish, and polar bears. This is becoming a serious issue in my Minecraft world as I am losing level 5 villagers I have traded with many times, and I am losing some of the animals in my zoo. Please fix this, it's now to the point I no longer want to log in in fear it might cause more animals to despawn while playing. I can verify these mobs have not escaped or died.
