I am working on this quest and when I got to the last step (Cobalt Scar - Salt Breeze) it will not update. I deleted the quest and tried it again and it still will not update.
This particular Yun Zi quest only requires the player to hit exploration volumes, JanEQ. You were likely thinking of one of the others where you are collecting trinkets from locations. Shanaa, I was unable to reproduce your issue. When on the proper part of "Ice to See Velious" Salt Breeze updated the quest for me. It is possible that you had accidentally skipped the previous part, since the quest journal update is purposely vague. But I'd encourage you to go back and try it again, if you haven't completed this quest by now. ~ Kaitheel
