trying to build a house i'm trying to build a house with L shaped stairs on a foundation next to a wall.....i've got it all done but for some reason my wall next to the stairs slopes and i can't fix it....when i try to level it, it levels the landing for the stairs to the height of the second story floor which throws my stairs off....please help me!!!!! i've followed tutorials too and it still won't work for some reason.....
