App doesn't work keeps shutting down. I started playing in November and about once a day the game would stop working and I would lose 5-10 minutes worth of progress. Then after an upgrade it stopped working for about 2 weeks in January. Today they launched a 3 day event and after a couple hours now I can't get the game started. It would be nice if they would give us an extra day for the event. If you haven't played yet pick another merge game there seems to be lots of alternatives out there.
