I got a realm for a month just before the latest update. Since the update the game has broken to unplayae on my realm. No animations for mining or sounds, things like buttons and so on don't respond meaning I'm locked out of parts of my base. Items don't drop, e.g I dig up a carrot but get nothing in return. It also randomly disconnects me now too. 

I have tried reuploading a back up from the realm, the original file uploaded when I first opened the realm and a new world I created today to check it wasn't the save file corrupted on that specific world.

I'm attempting to fix by reinstalling the game but I don't hold much hope.

Note: I am running 1.12 apparently but can't pick anything like that in the versions menu.
