When I talk to the last of the faction representatives before the council meeting, the cutscene that plays skips all of his dialogue. Immediately after that during the meeting, the cutscene doesn't show the start of the vision it just cuts seemingly randomly into it.
I presume you mean the guy called Surespell (from memory; could be wrong) that is in front for the Council building only at that moment: he says only one line and suddenly you are in the Council meeting for mission 2 I believe.
He then moves to his spot in the inn (second floor).
That super short dialogue was odd and did seem cut short by the Council meeting. The journal also shows only one line of dialogue.

Got the same bug, the last faction guy doesnt even get one word in it just cuts all his dialogues out with the NPCs replying to no one on their own. Then the council starts ok but suddenly it cut to a fight and it seemed like it skipped a part where some hero and monsters appeared? All the council is busy doing a spell but none of them had started doing that in the cutscene when it jumped to the fight.
