Love the game! Was very odd, refreshed browser as a few of the buttons would not function and lost all progress but then just waited a half hour and came back to the game and all of my progress was restored.
Just a note to all those having problems with offline progress - i was using IE, switching to Firefox seems to have completely resolved the problem (really doesn't surprise me much...).
