I had a lot of oincs and decided to redecorate and wanted to see if the placing wall art problem had been fixed, but I guess that category has been removed. So I decided to do windows instead and, much like the poster problem, it wouldn't fit to the wall. Although you can actually build it! It just sort of hovers in the wall. Hopefully this one can be fixed and not taken away because I love the bigger windows!
