I suspect the devs are aware of this to some degree but looks like there are still some persistent issues there.
There have been multiple instances where doing/saying just one single thing a companion character reacts positively or negatively to will gain +1 or -1 influence in their eyes and also immediately trigger a sometimes wildly out-of-the-blue conversation. For example, Tekehu and Maia can still proposition you literally within minutes from recruiting them -- and I mean, I could even believe it's somewhat in character, but it still feels kinda jarring.
Once I also let Xoti harvest some souls in the middle of some dank, dangerous swamp and she started basically Talking About Our Relationship while a bunch of forest lurkers attacked us even though as far as I'm aware, I had never encouraged her romantically in any way. It was sort of hilarious, actually.
Xoti's dialogues seem to be kinda bugged in general, I feel like her quest can proceed (or at least her quest dialogues can trigger) much faster than it probably should in relation to the main quest. Especially considering it's tied to it. For example, she seems to magically know what Eothas is up to before you've even had a second chat with him, let alone a third. I mean, sure, she's a priestess of Gaun, but... You get the picture. (And then there's the "wants to talk" icon that leads to nowhere.)
Aloth seems to be a bit better now, but he only ever seems to like Dutiful things and dislike basically everything else. I might be wrong, but I don't think even he should be quite that Stereotypically British. But I know it's a pretty huge overhaul to do to add more dispositions to him to balance things out.
Does anyone have other hiccups like these to add?
