I typed out a long post about my searches and coming up dry, but the forum ate it. So, I'll leave it short this time:
Is there a way to give colonies and capitals the spy-warding effect of a counter espionage building? Or, is there another way to limit spies to their civ-wide general spying (or turn them off completely if need be). I've tried setting <CanHaveAgents> to 0 for all buildings in Data/English/PlanetImprovements.xml but it didn't seem to work (might have to start a new game?).
Thanks
