I selected Seattle and then used nodefinder to see missing nodes on the south of the city. A node showed up at the very southern border. When I clicked on it, said Myrtle Way - White Center. (I.e. not a node in Seattle.) City Strides shows Myrtle Way in Seattle 100% completed. It is just this one point that seems to show up from another city.
I trird to take a look, but can’t even find a Myrtle Way in either Seattle or White Center?
