seems to fault when using darkmoon turtle. All abilities do not work as if selecting pass button or an error where nothing happens and turn is reverted to oponent. Oponent gets unlimited turns until pets are dead.
Same thing happens to me, where I should win, but opponet gets as many turns until it kills me
I experienced the same problem a day or so ago. I use the pets Little Black Ram, Snow Cub, and Spirit of Summer. It happened to me 3 pet battles in a row where the opponent got unlimited turns until I died. After the third time I relogged and I haven't had the problem since then... So I suggest until Blizzard can fix this problem, if it happens to you once just relog.
