Entities disappearing when loading back into world

There is a bug in Bedrock that causes different entities such as horses, cows, sheep, and chickens, to disapear which has been happening for the past few months and I am someone who makes attachments to pets in the game so it becomes really depressing when I go into Minecraft and go on adventures with my horse, only to see he's been deleted from the game permanently. This also gets really annoying when all of my cows and sheep are gone when I've been spending hours to breed the amount I had. This is a really bad bug and its been out for months! I'm sick of spending hours to regain what I've lost only to lose again and again! And I now deep inside that no one will ever see this and that this bug won't be fixed, but Minecraft needs to start paying more attention to Bedrock. This isn't even the only glitch I've seen that's been out for months. Heck, we could even talk about the arm glitch where in multiplayer your arms will come off of the player and float in front of them. That glitch has been out for almost 2 years! And until this bug is fixed, i'm scared to even try to tame a pet in fear of losing it to a dumb bug that Mojang refuses to fix. Honestly ruins the game and makes me lose hope in Mojang. If you finished reading this please spread the word. Maybe if we get enough people to talk about they'll finally fix it.
