Trail of Corruption act 2 bug

I'm trying to use the horn to clear the sandstorm in act 2 but I never get the prompt. I also was not able to use the desert map to go back to the sand storm either. I would get a loading screen and the animation of the caravan slowing down but the door would not open.

Using the waypoint in the previous zone and fighting my way through also did not work.

Disregard, I figured out it was at the front of the caravan. Seeing if i can just delete this thread
