Hi, I have been playing this game with my daughter, we are on level 25. We keep 'loosing' dragons, they just disappear. I wondered if they hadnt been fed enou do they disappear? But I can't find anything in the game details to say that and I would have thought there would be some notice on screen if that's part of the game. The final straw was her favourite carnival dragon disappeared when it was nearly fully evolved, so disappointing. Does anyone know why this happens?
