About the "where do I get an item from" part..you do realize that Gridania became "Maelstrom Command" with one of the latest updates?
Gridania quests and NPCs suddenly are shown as being in Maelstrom Command, so it also says items sold by those NPCs are sold there (which would be in Limsa Lominsa) instead of Gridania.
Or is this just some bug only I am getting?:o
