I've just finished my current game as the Scions. Not because it was over but because it has become unplayable. (I guess I have already reached the point of dominating anyway but I wanted to bask in my civ's greatness a little longer) Early in the game I ran into a repeatable crash that I could just not get past even if I went back a few turns. I went into the world builder and tried deleting all the animals on mountain peaks (there were quite a few.) but that didn't work. I remember someone mentioning problems with lizard units causing crashes so just for the heck of it I tried deleting the Cuali civ. I was going to try the Mazati next but there was no need. After deleting the Cuali, my game ran crash free for hundreds of turns... But, after awhile I started to experience a few non-repeatable crashes when ending turns. After awhile it was happening every couple of turns. I haven't had any slowdown issues and when it doesn't crash ending turns doesn't take too long. The only thing I notice is that even though there are no wars going on, the AI seems to be casting tons of spells/summons. I can hear a whole bunch of sound effects going off when I end the turn. I only have 13 civs left on my large map but the file is too big to post here. (2mb seems to be the limit) Still, I wonder if any other people who play large games or even smaller games have this problem?
