Right now in the two clients the roof levels are offset by one. This means that house designs that work in one client, don't work in the other. This really needs to be fixed. I just wasted a couple of hours trying to fix a house in the enhanced client that had been constructed in the 2D client, and I couldn't do it. What makes this issue worse is that you can get into a situation where there are no red tiles anywhere, but the house design won't work, and in a complex design it can be almost impossible to find where the problems are without starting over from scratch. It is extremely frustrating.
