Ubisoft are lazy thieves. Having removed the game for a little while I reloaded it. All achievements have been completed yet all my dragons have gone. Despite this ubisoft say it is once achievements are unlocked they are unlocked.... so it cannot save the game but can the achievement, and yet you must show receipts to prove what they have lost! It was linked to fb and Google but still I have to prove to these thieves because they cannot maintain their game. Utter joke
