I was recently questing in AV and I came across a problem. I was in a boss fight and you know how they auto choose a card. Well the timer ran all the way down and he didnt choose. And that didnt change at all. The bosses name is Mord RoughShod. He let the timer run down and didnt attack at all which isnt supposed to happen.
This happened to me and a friend in the White Owl Tower last week. The second boss stopped attacking us after we killed her minions~ never seen it before, but glad I'm not the only one who has had this problem.
