+1 on this. My daughter has been fighting his bug for a month now and has caused her to miss a project. She is now doing her final now and has to do this not logged in and saving via download picture every hour or so to not lose her work (again).
As a professional in software development this is exceptionally frustrating, and not the experience we need to be giving to novice developers. Fighting our own bugs is bad enough, but when the platform is destroying your work this can completely sabotage any excitement and joy.
