That quest is not a part of the Wetlands guides and it’s not in any of the Wetlands guides.
    It’s part of the Hillsbrad Foothills (31-32) guide.
    Pick the guide you were working on and if necessary , click the red buttons in the guide window “reset – reload” to get back on track (you may have to manually tick the travel steps – usually one or two).
    When the guide suggest window pops up, make sure you click “not now” as clicking the “go to” accidentally can mark the zone as complete. It’ll stil go to the next chapter.
