I have a level 2 provisioning writ for Seaflower Tea and Pellitine Tomato Rice. I acquired both items from my guild store/bank and also bought a second Pellitine Tomato Rice from an NPC vendor. Neither is being recognized as being obtained for writ quest completion purpose. It's my understanding self-crafting isn't required for provisioning writs. It worked fine for the level 1 provisioning writ I turned in. I either crafted or bought Surelie Syrah Wine, but I'm positive the Fishy Sticks came via mail from a guild friend.
Why isn't the writ being recognized as completed? The only difference I can find is that the Fishy Sticks were obtained via mail whereas the Seaflower Tea/Pellitine Tomato Rice were obtained from guild bank/store and an NPC vendor. Is there some sort of bug that allows the writ to be completed via items obtained via mail but not purchased or taken from a guild bank? Has anyone completed writs with items purchased from an NPC/guild store or from a guild bank?
