I had a bug once, when I went to Tarsen and M'lak, during the battle, I died. Then I respawn and came back, Tarsen was stuck in a scanning animation, and could not be killed. After he went down to 0 health no damage was displayed in damage, and M'lak was stuck near the door, before I blew it up.
I beamed up then back down, so it was a minor bug, but i'm reporting it none of the less.s
