the disrupt skooma trade quest.

I went in the cave before and wiped it out before I did the quest.

the dungeon still says cleared and nobody is hoome

what do I need to type to have the savegame recognize that the quest is complete?

and going back to an earlier save is not a good idea at this point.

If you're on console, then you're [censored] in the ass. I found that out 20 hours after clearing the cave.
