Maybe the recent patches & hotfixes broke something. I've experienced some dialogue weirdness on my dark urge playthrough, and while I didn't pay it too much attention, because I already know the story, it indeed looks like some camp scenes were triggering too fast. Example (spoilers because OP might not have played this part yet)
Astarion's midnight snack attempt happened on the second rest, while the party was scouting the crypt near the beach.
Obviously it made no sense this way, since there was no build up leading to this scene.
