I'm trying to do the NCR questline from my old character but it seems to be bugging out on me. I reloaded an old save point from right before I went into the El Dorado Substation to divert the power for House and I was hoping I could try to do the NCR quests so I looked at my opened quests and all I had was Oh My Papa, The House Always Wins VII, and a few side quests so I tried the Oh My Papa one but it won't let me convince Regis to side with the NCR and when I kill Papa the only subjects I can talk with Regis about is Good-bye. Is this a bug? I've already killed Karl and I couldn't use his journal at all. Any and all help is very much appreciated and sorry for any spelling mistakes, I'm on my iPhone.

Once you hit a certain point of helping a faction you cannot help the others, since they hate you for helping house. Its the same for helping other factions.

Yep, the point of no return. You can either restart from an earlier save point before you committed fully to House, or just go with the flow and finish up without doing any more NCR stuff.

Yup, you try and backstab the NCR and we will come and find you. :flamethrower:
