I was enjoying this game, nice way to pass the time, HOWEVER... At least once a week I open the app and everything I've done the last time I played is undone. Just happened again and I lost about 100 dragon power-- I had been saving up super dragon eggs/fragments to merge three together, finally got the last fragment needed yesterday and merged everything. When I opened the app today it was all undone EXCEPT the two super eggs and the egg fragments were all gone!!! Super upsetting.
