Did you have any mobs, whose health should be going down, freeze up and become somewhat invincible for a time? I've experience a couple of Dungeon bugs right after a case of monster health freezing happens.

actually no, we just beat Batrall and went into the cs. then we all skipped the cs because we've seen it so many times. after that everything froze up except chat. after about 5 mins we were booted from the game from a server error. later that night one of our pt memebers told us that the kill did not count for them.
