Bug? Or out-of-date wiki?

Trophy hunting. I'm having trouble finding the last trader in at least three areas. I finally broke down and checked the wiki and I have all of the ones shown there.

• Bergen Village: 12/13
• Basin Keep: 24/25
• Gaia's Garden: 5/6

For example, Gaia's Garden shows 5+2 on the wiki. I have the 5. I assume the DLC's 2 aren't tracked so the wiki and I are missing one.

Edit: Just found out that it's trade lists and not traders that is tracked so I need to go back over everyone. This would also explain why I sometimes got two when I check one trader (list is updated so I got the old and new).

Edit 2: Confirmed. The traders I was "missing" were simply ones that had updated.
