So I'm going through the Boulder City Showdown Quest and kill all of the Great Khan except for the last two in the room beside the hostages. Before I kill them I release the hostages who in turn attack me. With no one to help and reloads not fixing the problem I have to kill them.

Now when I enter the Hideout to kill the last two Khan members I automatically fail the quest. I don't know what I was thinking but for some weird reason I thought that Obsidian might actually make a game without any A Block level bugs so I have only been quicksaving the whole time and now I'm screwed(cant do the main quest now).

If anyone has any tips or any ideas please let me know. I could really use the BaseID if anyone has it so I could restart the Quest through the console. Thanks!
