I cannot finish You Can Depend On Me due to the fact that I do not have a dialog option to do so with Doctor Hildern.... Also as a side note Boone has disappeared on me, no he isnt anywhere in Novac or at the Lucky 38. Just adding my disappointed.

Yeah, I am in the same boat. It is because we finished the Tall Grass mission before doing this quest. From what I can gather, there is no way around it. Worst part is, without completing this quest you can't do other quests. For instance, you can't get Cass as a companion because of it. I am hoping some patch down the road can fix this. The only thing to do is start at a save that you have before Tall Grass (or whatever it's called). I did that mission WAY too long ago so I am going to have to hold out until then. Bugs that keep you from doing quests is more than an irritation for me. Hopefully it will be fixed soon.

I'm having this problem and I would really like to get Cass as a companion. I'm surprised this hasn't been fixed yet :shakehead:
