The issue is simply. Even if you have set your spawn point at the Temporary Grove, Nantula won't acknowledge your character to live there, to the effects of the gathering quest.
Could this be solved? unless it's meant to be this way, which I doubt.
If your spawn point is Gaeserics then she'll recognize you. Though, you'll spawn in Gaeserics. It might be the fact that this is a "temporary" camp, and these npcs will not be there much longer. Maybe maybe not.
