Also, the tube does not look like it was reinstalled with the best (angular) orientation: the broken rail endpoint is about an inch to the left of the bottom centre of the tube. Is the rail and the wheeled boat necessary? Perhaps the rail and the wheels could be removed altogether, and the boat could just be slid back and forth on the bottom of the tube (with a lowered centre of gravity due to the removal of the wheels); it seems to me that this would be a much more stable configuration!

The FG is not flowing any more and I can't turn it on. The tube was enabled.
