Recently I was playing on MCPE (a survival wolrd) and every single creature that was on my village/base despawned, even tamed animals like my dogs and cats, I lost all my villagers, farm animals, pets, mounts and my precious blue axolotl. I really don't know what happened and if it had something to do with my files or maybe just an in game bug, there's not much that can be done now but I wanted to know if there's a way to avoid this from happening again.
