There is a workaround for this problem, it worked for me at least. Just clear cookies and switch off all Auto-fills. I have no idea how Auto-fill affects the saves, and the author is pretty positive that it shouldn't, but it does somehow. I have a clean browser on my laptop for the purpose to play this game only :D Just finished reading through the new version, "The magic bug" never happened. Also in my experience it didn't happen in Safari browser on iPhone with default settings.
