Issue Wallpaper&Floor Bug

[ribibbi]

Hello,
I have a problem with the wallpaper and the floors in my house, that started after upgrading it. Basically, I can´t put any tapestry or floor to the new rooms Robin can add optionally(the northeast cornerroom and the southroom). The wallpaper behind the crip also bugs out. I´ve googled and found a few people with the same or very similar problem, one of them verified his game files on Steam and it did work, I tried this and it did´nt work for me I mean, I can still play and it´s purely cosmetic, but I would still like to decorate my farmhouse properly.

As far as I know, I have no mods that change anything regarding wallpapers or floors, but here is my Smapi log nonetheless:

I´ve also added a screenshot to show you a part of the problem:

Though you may want to start by removing the CompactBathroom mod, and see if that works. As the page mentions the mod having similar issues with flooring in the past.
