I have a mod that increases the costs for Great People. I play on Marathon and don't like seeing industrial age great people roaming around in the classical period. It worked prior to the update, but is no longer. <GameInfo> <Eras> <Update> <Where EraType="ERA_ANCIENT" /> <Set GreatPersonBaseCost="60" /> </Update> <Update> <Where EraType="ERA_CLASSICAL" /> <Set GreatPersonBaseCost="160" /> </Update> . and so on. What can I do to get it working in this version?
