All my mobs such as horses (with full armour), chickens, cows, pigs, and donkeys just disappeared. From one day to another. And now that I just logged in, from the 6 tamed horses that "survived the bug" i only have 2 left.

Literally I have a castle all with different pens full of different types of mobs. I have a stable where I saddled about 10 horses all with diamond or gold plated armour. However yesterday I logged in to check my castle and all the mobs. except for my sheep and 6 horses. We're gone! And today when I literally just logged in, I only found two horses in my stable. All the others are gone! This is really distressing and makes me want to not open my world again after hard work was out in and it was all gone! 

i also found out that some of the items I’ve placed on things such as signs or frames or  even armour stands have disappeared as well! (Example, I had several stands around my castle but in specific 3 armoury stands with all my enchanted armour and with my enchanted sword and bow and now it’s gone! I had to by the throne (acting as guards) and behind my thron I had my three armoury stands (which only one is left there with just the diamond helmet). What is going on? This really is making me just want to stop because all my hard work is just going away by a bug😞 any way I can get my stuff back?
