After getting all 3 companions, the achievement doesn't pop. Then I can't talk to Dog to add/remove him from my party. He just says, "let Dog free" or something like that. The game is acting like I never recruited him at all. I tried loading an earlier save and doing the quest again, but it does the same thing. And I can't just ignore it either. The next quest won't pop up. I even tried killing him, but it doesn't do any good.

On top of that, my level cap was never raised even though the message said it was. I still can't go past level 30.

I have the latest update. Sooo... yeah. I'm feeling a little ripped off here. I didn't even play it any longer than 20 minutes or so. Any suggestions?

I have had the exact same issue. I've gotten everyone else, but I can't remove Dog from my party. Since I have no saves prior to Sierra Madre, I'll be rather upset if I lose this character. Is there a fix for it?
