So, in my current run I executed Preston and gang, and that quest sits on "Failed: Talk to Preston" . So when 4.0.10 dropped and I finally had a reason to go to Vault 81, I headed off to meet the new NPC. I started Vault 81 being the good girl (I can be a douche to adults but ripping off a kid to get her stupid cat back is a level I am not at.) . I got Ashes back, gave blood to the good Doctor (and not, as Caleb (from Blood) said, somebody else's) , and went to do story time with the kids. Katy introduced me and when the first kid was suppose to ask a question the whole thing fails and nothing happens. No questions, no storytelling, nothing. I am wondering is it due to the fact the story revolves around saving Preston and fighting the deathclaw? As I executed Preston so I didn't exactly save him, per se, more like 'saved him' as Jezebel said the Mechanist's robots were 'saving' the Commonwealth. >.<
