Killed all the Stormcloaks at Hjaarlgard (spelling?) Camp but for Arrald, the leader. I knock him down and he keeps getting up and fighting again. Each time he falls down, his health line disappears and after a few seconds he jumps up. Anyone else encounter this?

From what I've read, you can't kill any camp officers. They're marked as essential due to once being part of a quest that was never put in the game. Or something.

OK, Thanx.
