Dead Money Heist of the Centuries Bugged?

[relax with my horns]

Hey, so...

I probably messed something up. I think I noclipped during Christine's part, because I got bored and I missed something. That, or I missed a terminal or scripted event somehow while trying to get to the vault in Dead Money. Now, (I swear I had a few manual saves while I was playing in Dead Money, but they're gone...) I only have an autosave and a quicksave...both of which are after talking to Father Sinclair.

That's important because it means I can't even use the Vault terminal to get the bad ending of the game. I MUST kill Father Sinclair. The issue is that now that the quest is bugged, when I leave through the elevator by the vault, it takes me back to the suites and my quest marker still points to the vault, and it remains incomplete.

I don't know how to escape Sierra Madre unironically now...if anyone has suggestions, I'm open to them.

I tried to use questcomplete, and my console doesn't recognize it as a command? I'm just not sure what to do from here. I don't even care about the gold bars or half the stuff I got in the Sierra Madre, I just want out and to get back to the base game.

(My last save that's before that one is where I'm level 9, from probably two years ago or so.)

Could use some help please!

Search this up on these forums. There's been lots of posts about it (you're correct in that the bug comes from using cheats in the vault to bypass areas, most notably TCL command) and people have posted the console commands you need to input to fix it without reloading a save before going in the vault

I can do that, but if it’s got anything to do with the questcomplete console command like on the posts I saw last night, my console throws an error at me telling me it doesn’t recognize the command.

I hate talking to father sinclair, especially since he's not a real character and exists only in my head (this happens alot) and I think has been one of the main reasons I've no progression in a while
