I found a strange bug:
I was in the Rainbow Tournament, in the last fight. By some strange way, the monster that my enemy was placing/destroying counted as mine too, and in that way i completed a in-game quest. Ok, one minute later, i used one of the stones that evolves all cards of its element, weeeell... My enemy cards evolved too. It looked like i was synchronized with the Ai.
I dont know if its a bug or not, because i never saw it.
