I have this too, and I notice that Proxyuser fills up all the "eggs", completely with crosses except the first egg, which it never touches. At this point, Proxyuser goes on searching, apparently fruitlessly, and never disappears off the screen. When I climb to 2000ft I can see the black hole I'm in, but further out there is visible scenery. This is apparent in Services 1 and 3, and started occurring yesterday (Sept 7)
