I haven't figured out why they disappear, but the hotspots for the buttons in the menus will disappear sometimes. The must be some case that I didn't think about when I made the hotspots. It would've been easy to make a mistake, because the Node within the quad tree for the hotspot that is selected will be taken out and placed within a list of the selected hotspots. Then when the hotspot is no longer being selected, the hotspot data was to be pushed back into the quad tree. Good luck with this one.
