Thanks for the help, I'm still not able to fix it though. I don't think I fully understand what you mean by pulling the exterior wall over. Did you have the 2nd floor exterior wall take the place of the triangular attic walls? I'm still playing around with it and the problem seems to come from either where the 2nd floor exterior wall ends, or where that wall meets an attic wall. Should I not have attic walls the same elevation as non-attic walls?
