So, the NPC Proctor Ingram refuses to start a quest conversation on the Mass Fusion quest.

So, that's basically what I'm getting as error.

I don't know it that's any helpful to you (that's from a forum btw):

You (I did) go back to just after (if you followed the brotherhood) kill all of the railroad people. After you smoke them out and talk to Kells(or maxson, I forgot) you'll get your next assignment with Proctor Ingram.

When you talk to you listen to ALL of her dialogue, this'll make it to where she isn't glitching out on you.

I could try this, but personally I'd like to keep the railroad. Am I right if I say if I side with the BoS I'd have the railroad as an enemy either way? (Like, in the confirmation message before you board the vertibird)
