Ive been playing my own world for a few weeks now and I've been noticing that some of the pets that i had "named with a name tag" out of nowhere and no where to be found its like they despawn but any mob that is named should not be able to despawn even these villagers that i had box "had been traded with for awhile" But like they just despawn out of nowhere i can't understand if this is because i don't exit and save the world or it just happens because of a bug please try to fix at least. Thank you
