I was at the Sylphic Vendor and can no longer just purchase items with Gil. I am done with theses tribes and have been for almost 2 years. I have no classes that gain anything from doing these quests and it absolutely ridiculous that I should have to do them to buy items that have always been bought with Gil.
Ok I just checked all the 2.0 beast tribes and none of them are allowing Gil to be used which is funny because I bought bomb ash from the Kobolds this morning with Gil and now I can't.
This is apparently a bug as I have finished the 3.5 Allied quest and had bought the bomb ash beforehand.
