To this day this bug is still an unaddressed problem, in specific, farm animals, mainly horses, chickens and rabbits keep despawning in conditions that should prevent it, including skeleton horses being tamed and name tagged still despawning, while rabbits and chickens also despawning for no apparent reason, in example i have 2, small enclosures to farm those 2 friendly mobs, but each time i turn around there are fewer and fewer of them each time, and no mobs that threaten to kill rabbits or chickens can even get to them. This bug simply makes it impossble to have horses rabbits and chickens as they just despawn even after being breed/tamed/name tagged, please address this issue.
