Mobs/Pets Disappear

Sometimes when my game crashes or just restarts, I go back into my survival world and whatever tamed animal(s) is around me disappears. Either it crashes and I get kicked out of the app, or I just manually leave to go on another app and come back a couple minutes later and the game has to reload. The animals never return, and there is no chat log stating that they died or anything. This has happened multiple times in different worlds with my horses, making me lose my saddles and horse armor. It’s been happening to me for a while with horses, but not often so I never reported it. However, it’s been happening a lot the past couple weeks or so, I’ve lost three or four horses in my current survival world when my game crashed. Most recently, this has happened to my parrots, once when I went to the nether my game crashed and the last of my seven parrots that I pushed through the portal disappeared, and was not back in the over world either. Today, I went back to my world for the first time since yesterday and all five of the new parrots I had with me were gone. The other day, I had just gotten a panda into a boat when my game crashed, and when I went back in both the panda and the both were gone. The same thing has happened to villagers that I’ve had in an enclosed and brightly lit space, such as the one I healed in my igloo basement, and they disappeared. Most of the villages I find usually has only one or no villagers, but isn’t an abandoned village, which is also pretty annoying. This hasn’t happened to any of my dogs or cats yet, however, just horses, pandas, parrots, and villagers.
