Hey, quick question. I finished Oh My Papa by having the Great Khans leave, but the quest For the Republic, Part 2 updates that they were destroyed. I then tell Moore that I took care of the Khans, but she talks as if they were destroyed, just as the quest says. Here's the thing, is this supposed to be the way the game plays out, or is this a bug?

As far as the NCR are concerned, Leaving the Mojave is the same as them being Destroyed. All they want you to do is deal with the Khans one way or the other.

Note, I think this is one of the trigger quests to get the Legion Hit Squads to come after you, so be careful about completing this Quest Dialog. These squads will come by every 24 hours, and can clear out areas like the 188 and Grub and Gulp on you, even if you are not in the cell. If your on the PC, there is a mod that makes them come by once a week or a month like they are supposed to.
