Go! 2.0

Hey all,So, I updated Go! this morning, and everything has changed. It's a full reset, pretty much. I still had my gold and crystals, but the whole thing is TOTALLY revamped.Am I missing something? Will old screens return once the campaign is done? Or has Rovio basically changed the entire game into something new?For folks who had a massive number of challenges completed, is that all gone now?Shouldn't they have simply made a whole new racing game and left the old one alone? What am I missing here?Thanks, sutekh137
