Dissipating animals,auto dropping items,and carrot on a stick not crafting

I have been constantly set back on my PE world because i will be doing what ever and randomly a item will drop it self making lose heavily enchanted bows and other items. The worst thing is when my game crashes mobs dissipate I had a village next to my house and maybe one or two would dissipate every crash than suddenly only one villager when 3 minutes ago there were about 15 this also happens with sheep and horses I had a horse with gold armor and named put into a pin and tied down dissipated making me lose the saddle the armor and a horse I loved a lot the same thing happened to 3 more lamas and I had a sheep collection going and when I had about 10 but only 3 survived to get to 1.12 or 1.1.2 but I named them The 3 Sheep of The Apocalypse and than dyed them according but the dissipated all at once I know they didn't despawn because I bread and feed them. Over all this problem has continued to ruin my game experience and time to where I might just quit but I would prefer you it fix it you did some thing right at 1.1.2 because it slowed down but still happening I put my seed into a picture and also a pic of a carrot on a stick glitch and the pen for my animals but also check the hot bar with the carrot one it's also annoying
