All of my tamed animals in my survival world disappeared after the update which sucked because I had collected basically every type of tamable animal and had name tags on them too. 
(farm animals, cats, parrots, axylotls, wolves, tropical fish) 

it took me a long time to get every variant of every animal too so I’m super bummed. Went out to an ocean biome to get more tropical fish for my tank and got some nice colourful ones but when putting them in my tank they came out all black and white? 

So upset because my world was practically based around collecting every animal and it took so long especially in survival world. I have tried logging in and out and yet no change.

Also just before the update I had received the max amount of sharpness IV books from a librarian villager I had kidnapped and combined them into about 6 sharpness V books and since going back on my world they all disappeared from my chest. 

Please help because I loved my world and I hate having to start again and then not even having that work out with the fish.

Attached a photo of the fish and of my empty farm below. More upset about the parrots and the cats though because I had every variant of them 🥲
