My mod crashes during the Renaissnce, no idea why

At first I thought it might be a MAE caused by so many civs in one game, but the last game I played while testing experienced the same era, and there were far fewer civilizations than the game that orginally led me to that conclusion.

Windows 7 does not tell me what causes the crash, so I'm left scratching my head about this. I have seen that sometimes Modular loading civilizations and the Revolutions mod(including the barbarian Civ component) do not mix. I wonder if that has something to do with this.
