Yeah, maybe - I just killed him while he was in my party. The "quest" & warning dialogue started. Then I just long-rested 3 times.
Well, in any case I'm surprisingly impressed they actually addressed this detail.
Honestly despise venting about how much I disliked the incongruence, I assumed it would remain forever one of these "videogame-y" things where they pretend everything is fine.
Just out of curiosity, outside of the "cinematic pending" how is the game over presented exactly? Some line of text, a pop-up telling you why it's game over or...?
