i have around 40 maps hanged on a wall in a room just below my bedroom, all paintings and frames just disappeared out of nowhere along with two lamas, two horses and a few cats and dogs but i'm not sure if its the same bug because they are around 60 or 80 blocks away.

but yeah, basically every day i open the realm, it all disappear, i luckily have made copies in a chest but i'm not trusting the game anymore enough to hang them on a wall again. 

Its only happening overnight so far, (when the server is closed), because we've tried to all log off and come in again and there wasn't a problem. i'm waisting a lot of time with this bug and its getting really annoying.
