When i picked a fightagain a monster able to do copycat i switched my pokemon sadly.

The foe runned another copy cat atk for an incredible illimited combo fof copying last attack.

I had to shutdown my game.

So I just left Cock Tunnel and I ran into the trainer right outside and her Cleffa did the same bug but the game fixed itself thank god. Also, is it possible for a pokemon to put itself to sleep with its own Sing?
