Tribunal: Urvel Dulni doesn't exist

I'm supposed to escort him to the Shrine of the Dead but he's not in the Archcanon's office, and opening the console and typing player.moveto [his refID] took me to his default editor location, but he wasn't there.  (So I placeatme'd a fresh copy, and off we went. Ended up having to placeatme a SECOND copy after I told him to Wait Here so I could scout our route, and he decided he'd rather walk off a cliff than cleanse the shrine. Maybe turn down his energy level so he won't move so restlessly, or reduce the range of his Wander AI package? Or pathgrid things so the NPCs know where they shouldn't walk?)

Also, in the Mournhold Temple Basement, Shunari Eye-Fly is already standing there, claiming to have knocked out the guard who's just standing there staring at her.** I haven't cracked open Gedna Relvel's tomb yet. (Also, as I haven't finished the Dark Brotherhood questline here in Mournhold because Tienius infuriatingly will do nothing but grin at me and say "excuse me" and make me really, really want to punch him in the face, you may want to mark the three "dark brotherhood" assassins in Barenziah's chambers as Initially Disabled until you get the questline smoothed out.

**I've been noticing that a lot of the dialogue/quest interconnections are screwy in Tribunal. The DB questline, as I've said, and the plague questline, and if I try to ask the armor maker for Ebony or Glass he just says "here's your helm" and gives me nothing and that's it. And I can't sell any artifacts to the museum.
