That's about the gist of it. Now, I went through there much earlier and might have killed Barilzar then, before the quest was initiated, so no Mazed Band on it. I don't know. But even getting one via console and repeated dropping and picking it back up didn't get anywhere. It could also be due to something glitched/unfinished in the Overhaul mod collection I have installed.
So I guess what I need is the way to get the quest updated through the console. How can I find the code needed to do that?
Thanks for any help.
EDIT: I also used the "Reset Actors"-RA console code, with no results.
