Im playing the early campaign, currently turn 182, year 1352. I'm playing kievan Rus and everytime i end my turn all is fine and dandy until the Kwarezmians get their turn and my game freezes up and i end up having to reset my pc

I noticed after 3 tries that the Kwarezmian are besieging the last Mongol city on the map. and that when it freezes at their turn it always freezes as soon as they conquer the city and the Mongols go horde again.

I think it has something to do with it, but i dont know where to find the crash reports on my pc, im using XP and im playing version 1.4 if that helps.
