First attempt at dry-fit

As you can see, I am having a little problem with the center wall floor . . . I think the foundation board is warped. I will take this apart and fix that!! When I was doing the dry-fit, I noticed some of my pieces didn't look the same shape as the schematic diagram. I then realized that whoever put this together the first time had glued little pieces of wood in various places . . . I think this is one of the reasons the walls and floors had so many gaps in them before I took everything apart.
