The bandits seem to largely ignore the player, until he or she stands in one place for too long. These are leveled bandits with the Ambush tag in their name.
The dwemer machines are a mixed bag. Outside of a scripted ambush they completely ignore the player. When scripted to pop out of a wall, they attack just fine. The centurions are all hooked up to docks, which are activated with a switch, and they'll follow the player but they won't attack him.
The giants are all LvlGiant and seem to work just fine.
I'm all of out ideas, so any help would be greatly appreciated.
Thanks!
