might be of some use to you
Edit: A post was added to the above link after i posted this,
For those stuck on the quest "Order Up." If you're stuck on Palomel(NOT Grevan), I've found that completing the quest "A Thirst for the Ages" would allow the correct dialog. A friend had the same result. So if you're stuck on Palomel, check if you have "A Thirst for the Ages" flagged.
worked for me!
