Lost all our dragons-very upset mom and child

This WAS one of my childs favorite games. He plays it ALL the time and has screen shots of over 30 of his dragons. Today when he tried to play, the game had completely reset and ALL the dragons were gone!!! Its taken months and months to obtain all these dragons. Child is understandably having a MELTDOWN. Mom extremely angry!
