after reading the forums and ppl saying the start of Uuna’s world tour @ the gate of the setting sun is bugged ( last i saw posted 7-6-2020) and no work around… the thought occurred to reset the vale of eternal blossom back to before N’zoth. (forgive me if someone has all ready posted this)
So, this worked for me.
In Vale of Eternal Blossoms go to Zidormi (80, 32)
reset to before and than go to the gate of the setting sun.
go to coordinates 8, 58 (right smack dab in the middle)
all the sudden worked.
the original coordinates in the guide say 8, 59… which put you off to the left of the gate. even 8, 58 put you to the left of the gate. when you revert time through Zidormi, 8, 58 is now smack dab in the middle.
hope this helps, and again sorry if i’m re-posting this.
