Forum:Broken quest

I'm doing the For the Republic, part 2 quest and in lieu of that, the 'Oh My Papa' Quest. I had the Khans kill Karl, and conviced all the influential Khans to help me. I spoke to Khan, and convinced him to help the NCR fight the Legion. The status of the quest is now: Go talk to Regis. Trouble is, when I do, the only progress I can make is ask him if he's willing to ally with the NCR. If I do, it completes the objective of Talk to Regis. Trouble is, now the quest just "hangs." I get no further objectives.
