The special thing about the fantasy ruleset is that it uses units with gold upkeep in gold cost. I realized something was wrong since the mod allows you do build units and lower your gold past 0 until you reach -70, then units are disbanded. The problem is that pay_for_units counts the possible gold that can be got from improvements later, but it miscounts because it doesn't check if improvements can actually be sold. This allows the city with palace to not disband units until money is under 0 gold with could be the reason for the crash (since new palaces are created after civil war etc..) Patch to 2.1 branch attached
