There seems to be some issues with party dialogue in general :/
We managed to get another member and start a 4 person file in order to avoid the AI auto-skip issue. This worked for a short time...
We suddenly started to run into an issue where *nobody's* dialogue would actually be voiced during party deliberation. Everyone would select their option and the game would immediately skip each voice line.
Unlike the AI dialogue bug this is very difficult to recreate and seems entirely random.
This is really frustrating and depressing because the voice acting in this game is superb (especially the Origin characters). Even though you can read and select your dialogue it leaves you feeling empty; like your characters aren't actually impacting the story or sharing their thoughts.
