*edit* Ignore, I found the button for node picking! So the description of the Naturalist's Survey action says that he'll investigate nodes you designate manually, otherwise picking them at random, but there's no way to select specific nodes. I imagine this is related to nodes changing from gold arrows to glowing rocks, recently?
Yeah. It's uh, not quite ideal. Will see what can be done to smooth out interactions here once we're done the initial rush of hotfix issues.
