Ocelots despawn

Ocelots despawn randomly from your world

Steps to reproduce:

1-Move to a chunk outside the spawn chunks

2-Make Fences and spawn ocelots (I tried with /summon ocelot)

3a - Go away from the chunk so all the entities unload and reload it

3b - You can also exit and re-enter the world

Result: Ocelot will have despawned
