Forum:Great Khans/"For The Republic, Part 2"

Heya, having an issue with recruiting the Khans to the NCR.

Alrighty, so got to the point where Colonel Moore is asking me to get rid of them (or recruit them), but thing the quest(s) are bugging out like hell. Here's whats happened so far:

1. I killed the Great Khans at Boulder City. Had no real idea of factions at this point (thought they were just like powder gangers and inherently hostile). This put me at Shunned. Great Khans at Red Rock Canyon won't attack me, but I can't the the Aba Dabba whatever quest line to deliver supplies I think. The girl won't give me the quest because she doesn't like me.

2. Way before the Colonel Moore/NRC quest, I visited the Khans and talked with the Legion guy, Regis, and papa Khan. No quests started up, but I did all the related "join the NCR?" dialogue. Nothing has happened since then and the dialogue is no longer there.

3. Now during the quest line with moore, there's zero dialogue from what is mentioned about getting them to join the NCR. I read up on quest info in various posts on here and other sites, but all these dialogue choices that are mentioned aren't happening for me. The "Oh My Papa" quest did start finally talking to regis (nothing different in dialogue, dont know why it started other then the Moore quest maybe) and going back to Moore, she just said assasinate the leader which I'm avoiding.

Note: The "Oh My Papa" quest only started after I talked to regis again with just going through his dialogue about the NRC again. I never got the "Regis talks to you after you leave" part. On further research, this only happens if you talk to Papa Khan about joining AFTER you get "For the Republic, Part 2"

With all that above in mind, here's questions:

1. Any way to raise faction with the Great Khans? Did all the science related recipes for hack and sent the kid to the Followers, but still sitting at "shunned".

2. Any idea what to do about the quests and/or bugs?

3. Any way to get Great Khan clothing without killing them? The Great Khan Corpses at the Tribal Village and Boulder city have all since rotted. Tried to assassinate a great khan in Red Rock but no go (just get villified)
