I'm working on a mod that includes a smallish gorge, created as a worldspace. I have a Dwemer tower at one end, halfway up the wall of the gorge, with a balcony. The door from the Dwemer ruins to the tower balcony USED to work, seemingly until I added a quest that takes place in the Dwemer ruins. Nothing in the quest references the door. Now the game crashes to desktop every time I go from the ruins to the gorge, even if the quest is not running (The quest isn't running at start, various triggers start it, to get around the dialogue bug.) This is supposed to be a house the player can win by completing the quest, and the balcony is one of the main features. I've deleted the door and recreated it a number of times, but it still crashes. The gorge worldspace is implemented as a 'small world' with 'fixed dimensions', if that matters, because I could never get LOD generation working right (I did try, might that matter?)
Okay, 'fixed dimensions' doesn't matter, I just tried turning that off. Still CTD. I should add, there are nine doors leading into this gorge at various places and none of the others crash. I've tried deleting the navmesh and recreating it as well. I'm trying turning off 'small world' now.
Thoughts on debugging this situation?
Edit: turning off 'small world' setting did not help. Didn't think it would. It is a small worldspace, and the cell with the CTD door is near the center, at (-1,0). It's not even the only door in this cell, the other, lower down, works fine.
