I'm trying to complete the quest Blind Betrayal - I've convinced Danse to live and as we walk out of the bunker we're supposed to confront Maxson. However, as Maxson is speaking, he just starts walking away and keeps going until he's out of range and the quest can't continue. Paladin Danse just turns and asks me what my decision is and I'm stuck with my gun lowered and my HUD gone but no dialogue options are showing up for me to choose from!

edit: I have re-loaded an earlier save to try and restart the quest twice now

I have also submitted a ticket to support so if I don't hear back from the community I'll post whatever suggestions they make here.

Suddenly I feel it appropriate to mention that, yesterday while I was out in the wasteland I encountered a different NPC who had dialogue options who just kept walking away from me until the conversation was forced to end so - maybe that is the overlying cause of this glitch: NPC's not knowing to stay put when in dialogue after 1.04?

I had this happen before the patch. I kept moving and kept blocking Maxon from advancing. It was a real pain but ultimately worked. So frustrating to try and keep conversation going while trying to keep him standing still. It is possible to get through it with him doing this, but you have the be blocking his movements as best you can.
