Hello

I am in trouble with the quest "Call of the desert".
In this quest, Miounne simply ask to speak to Momodi, in Ul'dah city. It is a small quest, just between Tam-Tara and Copperbell.

The problem is that when I talk to Momodi the "Confirm" button is grayed, I can only refuse.
However, I filled out the goals (I'm level 20), and the quest icon above Momodi is green.

It is a main quest, so I cannot continue the game since it is not fixed.
Is there someone experiencing the same problem, or having a workaround to suggest ?
