Continuity: Act 2 start - missing a quest or hint for how to continue

I arrived in Act 2 Vastiri Outskirts and killed the centaur. Now I am back in the camp and the new path "The Ardura Caravan" is open.

For continuity purposes there should be a quest telling me to go there / join the caravan / something. I don't have any instructions at all about what I am supposed to do right now.

I know it's kinda obvious as it is the only option. But in PoE 1 you always have such continuation quests too, so this looks and feels like an oversight.

Dont skip dialog or at least pay attention to voiceover.

I did not intentionally. See my other bug report.
And please read again. I said that in PoE 1 there are always QUESTS that lead you through the storyline.

Correct, a quest is needed, because of situations like mine. I had crashed or bugged or logged out or something and the instance I had did not allow the caravan to lower the door or whatever, no instance until I reset the zone. Confusing AF.
