I'm having trouble completing the "Shoot em in the Head" quest. I stole all the keys from Crowley, and agreed to the ghoul. When I go back to Tenpenny, he gives me the 200 caps reward, but...nothing happens. No experience is gained, the quest is not complete. I can get into dialogue loops with Tenpenny that make no sense, seeing that Crowley is dead, but there's no advancement/completion of the quest.
I can kill Tenpenny, and my quest marker will be aiming at the dead body of Crowley...so I'm in a severe jam with this particular quest.
Where I have my save point is, Crowley is dead, and I'm heading to collect from Tenpenny.
I did a little bit of reading, and it seems like this is a fairly known problem. But...am I screwed, or is there somethin I can do to fully complete this quest?
