Unfortunately the patch today did NOT fix the problem. Inez and Milverstreet still just stand there, and I can't get anything to progress.
Loading an earlier save before I cleared the drones, Inez still isn't in the room. Clear the drones and she immediately shows up, but the exact same problem, she says her piece about him fixing her arm, then there's no way to progress by talking to either NPC.
On the bright side after doing that my game no longer crashes when leaving the Incognito, so that's a plus, but I still cannot play until this is fixed. I assume because I completed Milverstreet's quest before Inez was in the room, and she was supposed to be there for that conversation.
