Thank you for those suggestions, we're on the right track now. I deleted the ground tiles, but I was still unable to drag the existing foundation out further. But, I was able to place more tiles and place stairs one group at at time. I tried adjusting the slider to place multiple stairs at once but that did not work. But this did! This is the main entrance to the school that most of the children try to use, so I am determined to figure this out. Some students will try other entrances and they work fine, but some will just give up and run off, skipping school.
