Some designer at EA goofed this (shocker).

I've seen a couple screenshots where people have used this floor without any problems. Either I was extremely unlucky, or this mistake doesn't show up unless you have your graphic settings maxed. If you didn't notice it was broken, you probably don't need the fix. It did, however, bother me: so I know it's irking someone else, too.



Oh, and clearly this isn't a door or a window. Nor is it really a recolor. There wasn't an appropriate category, so went here unless the mods can find a better spot for it.
