Hi, is it normal to not see the roof at all while in build mode? As soon as I click off of the roof to deactivate it like to turn the screen around or whatever, the whole roof disappears and I can't do anything more w/it. When taking one of my sims home from a neighboring lot, I noticed that the roof was all messed up, but when I go into build mode, I can't get a roof view to see where to correct it. Is this normal?
