Bug/Issue Unable to place wallpapers

When I opened the game after updating to the beta, I opened my year 5 save file, and all of the downstairs wallpapers had been changed to the first wallpaper in the list of the large wallpaper selector. I grabbed a new wallpaper from the selector, and went to place it, but the wallpaper didn't change despite it disappearing from my inventory. I bought the daily wallpaper from the shop instead, but the same thing happened. It happens with at least the first 3 wallpapers in the selection, but I haven't tried them all. I have a year 1 save file, but i can place wallpapers fine in that save. After some testing, I found that I can place wallpapers fine in the top left room fine, but no where else. I have all the house expansions, but none in my year one save file.
No mods installed, and i tried to fix the game files via steam, but it didn't help.
