No Companion Dialogue During Enemy Battles

Here's how I tested the combat dialogue based on your suggestion, EA_Shepard :

1. Loaded an earlier save with Neve at "Falling Hard" (romance-locked state) and then re-saved it as a test save.
2. Restarted the computer and game.
3. Loaded the test save.
4. Did ~9 battles in Rivain and heard multiple congrats dialogues between Neve and Taash, including Neve to Rook:
   1. Look who comes through.
   2. Now there's a nice shot.
   3. Well don't you impress.
   4. Nice move.
5. Restarted computer again, loaded same test save, same battles in Rivain; Neve was a little more chatty in combat to Rook:
   1. Rook, aren't you one to watch.
   2. Hey Rook, nice shot!
   3. Not too bad.
   4. Nice move Rook.
   5. Would you look at Rook.
   6. Well look at that.
   7. Rook takes credit there.
   8. Now there's a nice shot.

In previous playthroughs, after the romance lock, Neve had combat dialogues like "That's my kind of Trouble" and (iirc) other references to Rook as "Trouble". The dialogues that I heard above seem like the standard, non-romance dialogues. To test that, I loaded a much earlier save with Neve at "Longing Glances" before the romance lock-in, and I got many of the same comments that I heard in the later romance-locked save.

While I was in-game with the first test save, I also created a second test save on Tearstone Island and reloaded the save during that first play session. In ~7 battles on Tearstone Island, there were 0 congrats dialogues during combat, although there were multiple warning dialogues during combat.

I hope that helps. I'm happy to share save files, but the forums don't allow me to attach csav files. How do you recommend sharing save files?
