I crafted some Regal Castle Blocks and made a small house. I had trouble with the floor pieces accepting the floor tiles but finally got them on and they stayed when I left. The Regal walls are another story. I have tried for two days to get the wallpaper to stay when I leave the area but when I come back, they are red again. The wallpaper is still selected but it is not showing up on the wall. I select the wall from my backpack, move it into place, and select the wallpaper. The wallpaper shows up but when I leave the area, it disappears. I've spent 2 days on this, what am I doing wrong? I have 12 wall pieces, 6 window pieces and one invisible door piece. Only 4 wall pieces will keep their wallpaper. Any suggestions? Sophia
