I've previously made Papa Kahn and his gang distance them from the Legion, so to speak. The Kahns shot the ambassador in Papa's Long House and. So now they are willing to perform the suicide attack. Also have told Yes Man about this. If I understand it correctly the suicide attack will be against the Legion and pro-NRC.
After doing the I decided to travel to Hoover Dam base. I pvssyd with Colonol Moore, and se sent me for the quest: 'For the Republic, Part 2' (part 1). Requiring me to destroy the Kahns, as well as giving me a diplomatic option, right?
Anyways, at the moment I can't tell the Colonel that the Kahns no longer pose any threat to the NCR, and in fact are already willing to help the NCR in the upcoming battle. However, I also cannot open any new conversation options with Papa Kahn (nor his second in command) regarding 'For the Republic, Part 2' (part 1).
My question is: can I still complete 'For the Republic, Part 2' (part 1) at the moment for Colonel Moore? Or has this quest bugged for me now?
PS: Nevertheless, a fantastic game for the rest. Have had problems with two other minor quests before. This is the first major one.
