For some reason, I have some walls that won't accept windows. Or more specifically, sometimes they do and other times they don't. There are no objects or wall hangings in the way. At the moment I'm working with the Avalon apartment and the corner of the floor plan that's at the far right of the game screen is the back wall that windows don't hang on correctly. It's frustrating because I had finally gotten windows up there, but then I remodeled and the windows won't go back up now.

Has this happened to anyone else? Any suggestions?
