I've encountered a bug in the 'Birds of a Feather' quest.
Whilst guarding the Silver Rush, a guy named Pacer approaches and after talking with my fellow guard, he just stands there.
I tried advancing time but that didn't cure it.
Now BECAUSE I advanced time, I've lost my autosave before the bug.
I can't abort the mission as if I leave my post, I get my [censored] handed to me.

Is there a command to forcibly end a quest?

You don't have any recent regular saves?

i think you may force a fail if you leave your post and, say, slaughter the van graff gang

My last save was about 3 hours before.
I don't regularly do independant saves.
I just rely on quicksaves (the last of which I did when this guy approached) and autosaves (which I overwrote when I waited for one hour)

I know I'm a [censored] for not doing other saves but let's just say that I've learned my lesson.
