Just wanna warn people for a bug that we ran into today in CoT: Stratholm.

After the 2 first bosses when arthas is on his way inside, he walked up to smash down the human in the bar, he got aggro from a zombie outside that had followed us there and after that he just stod there doing nothing. Impossible to reset.

So, just a hint, before talking to arthas and walking into the bar, kill ALL zombies that might aggro the party.
