I'm doing the Walking Nightmare quest in Dawnstar and my guide "Erandur" walked into the front door and never showed up inside the temple, is there a code to reset this quest? Any ideas, I have turned off all mods..but he's still MIA...

Type the following command after entering the ~ key:

setstage DA16 30

enter then close with the ~ key. That should place you at the right spot to meet Erandur in the temple. There is an Elder Scrolls Wiki which I can't post any kind of direct or indirect link to which has all kinds of information regarding the game and commands needed to advance glitched quests. Google it.

Using console commands is not something I would recommand, especially commands that update quests. Reload your game before Erandur enters the Temple and enter before him. If it doesn't work, try these commands
