I'm having technical difficulties, and I just don't know what went wrong, and thus can't test this, but as far as 'splitting the graph' goes with nomads. I know that if you try to cut humanity off entirely from the AI then things go wrong FAST, but what about only partially cutting off? Two ideas/examples. Cut off your HW from AI space, and thus become technically unable to lose, but make sure a handful of other human worlds are still in the AI reachable grid. Would it still do terrible things? Final idea, on say an X map. Cut off one, and only one, of the branches, severing one of the AI HWs from the rest of the galaxy. What happens?
