>Found it. There were multiple conversations that seemed to be tied to the story.
Yeah the elevator talk can still get to be played but those mission specific dialogue don't pop up anymore. I asked around but got no feedback on it. I guess it must be tied to the campaign progress.
But I've heard weird tales of people losing their operations progress if they hit new game so I haven't done it myself. An anon thankfully posted those unique campaign progress lines for us.
