Glitch issue – Dungeon Boss Review

I got the demon legendary guy from the first Christmas door, but when I went to battle, the game lagged so it had to be reloaded. When I got back in the demon guy was gone, saying I have not unlocked him. Can you some how please get him back for me? My name for it is Jpender if that helps. Great game over all though.
