FIXED: Named walkable area points disappearing
Reported by John Green: Named points (like startpoints) seem to disappear in the walk editor. They are still there, but you can't see or select them, and thus can't move them.

This was a related issue to the other reported walkable area bug (floor points automatically joining). The source of the problem was exactly the same so I was able to kill two bugs with one stone. :!: Cause: The floor data gets processed during AS export (all points in a common floor box are connected), and if you were to save your project again after export (and before quitting), that compiled floor data was getting written into the project. :idea: Fix: so, I just did what I should have done from the beginning: make a copy of gamedata and compile that so the original editor data is left untouched. This fix will appear in the next release of the Copilot application file.
