The Vendor NPC locations seem to be wrong. NPC are being listed in the wrong location. Sounds like someone changed the locations table and didn't update the NPC locations correctly.
For example: Chomo Jinjahl and Kopopo are not located in Ve'Lugannon Palace and Melloa doesn't sell Baked Popoto from the Spire of Holla:

And it's not just that page.
