Priest Class Mount Scenario "The Seekers"

[Kaych]

WoW Freakz link: https://www.wow-freakz.com/quest_helper.php?quest=45789&&name=the-sunken-vault

Bug description: After a dialogue among the NPCs, Caretaker stops talking and the script doesn't continue, he should move around as the "sunken vault explored" part of the quest. I relogged and re-entered the scenario, but it doesn't work.

This is how it should work (min 5:53) https://youtu.be/-fuuDki-z-c
