The "Maximum Number of Systems" parameter in the startup screen is not working; it seems to default to 1000 no matter what.
To reproduce: Start a new game, set Maximum Number of Systems to 250, 4 NPRs at start, real world star systems off. Immediately after setup is complete, turn spacemaster on and go into the system summary view. The NPRs' starting system numbers have been randomly selected between 1 and 1000, as will all new systems throughout the game.
