Quest Issue: Stein of Moggok

[Flank]

In East Freeport, my Exotic Drink's quest turn in bugged when another player was also turning it in. I turned into Gregor Nasin: Kiola Nut, Erud's Tonic, Honey Jum, Koalindl Fish and it did not reward me with the Bartender's Compendium that it had done the past 4 times I've done this quest on this server.. retrieving these items takes many hours so I think this issue should be fixed.
