When I was in Ross 720 just about 1-2 weeks ago there were several jump routes leading there (Dumnona for example and Kokojina I believe). Now I can only get there through Lokitaka Mu and Kokojina isn't reachable at all - it'd just completely unconnected to anything. Is this a bug or is it some kind of gameplay mechanic that I'm not grasping, yet? Somebody please explain.
