Can you build a tower out of wood floors/walls and not have it glitch out and be uneven when u try to make the roof? Last time i tried to build the walls wouldn't snap properly on the second floor unless i removed all the walls underneath them on the first floor. Because if i didn't the walls i'm trying to place on the second floor will snap to the wall on the first floor. Instead of snapping to the floor that's on the second floor...
