This has happened to me 5 times this past week and iv had to make and replace the paintings each time. Playing this singleplayer Xbone world for like 3 months and it just started dissapearing my paintings this past week or two. I notice it when coming back to my base after adventuring for multiple ingame days, the paintings have just vanished, nothing on the floor and you can break the walls themselves without getting the vanished paintings, so its not that the paintings are invisible, but despawned entirely. Ive wasted too much wool replacing my 20 paintings every few days that im just giving up on using paintings at all now. Can the devs please take a break from their copper update obsession to fix the current game first?
Happening to my singleplayer xbone world as well. But I can make the paintings pop off by just saving/quitting the world, then reloading it again and the paintings in front of me will just be items on the floor when I load back in. Its so bad I cant even use paintings anymore because they dont stay up and is just a waste wool
