Trail of corruption bug and softlock in party play.

Cruel Act 2.

Killed water goddes together with friend, blown the horn, the sand storm disappeared for both ofs, but he didn't move forward on quest, his stage of "Trail of Corruption" quest is stuck at "Speak with Asala"
But she does nothing and he can't travel to Deshar.

And thus he is stuck and can't move on after playing so many hours...

Any solutions?

Would be nice to have reset option for quest as a temp solution for any possible bugs like this
