While playing through Oh My Papa quest and trying to make an alliance between the Khans and NCR the game tells me to speak to Colonel Moore about an alliance, but it does not give me any dialogue options about this. It renders the quest uncompletable. Please Obsidian, patch this bug so I can continue enjoying your epic world.
P.S. If anyone knows a workaround, please post it.

For me the New Zealander sounding lady has disappeared. Hope she returns with patch, but doubt it.

I finished this quest with no problem, I don't get why everyone else is saying it's bugged. I didn't even know this quest was one that was considered "bugged". It's not even that good of a quest.

This happened to me too. What you need to do is blow up Papa with some C4 or something while he is asleep (use a pip boy sneak into his room and stay there). Use the detonator when you are outside the building and the alliance will go forward when he is dead.

It is considered bugged if you completed the "Don't make me a begger" quest long before starting "Oh my Papa" and "For the Republic pt2" As Meliss would disappear yet the pipboy says shes at the Khans encampment.
Along with to the blowing up papa: could done so but my sneak skilll was low and i sold my frags, mines, and bombs.

Hard to complete the queste if Melissa ain't there.

Well first of all I'm trying to complete this quest diplomatically, which means no killing. And second I haven't even done the "Don't make me a beggar" quest yet. It is just plain old glitched and Moore won't give me the dialogue to make a treaty between the Khans and NCR.

I just completed Oh My Papa... if you kept Papa Khan alive all you can tell Moore is they dealt with. That would complete the quest.
