Whoa, that sounds strange, as I recall that game was under the following start conditions:
Type: Random
Size:Large
Research: Normal
Production: Normal
World Difficulty: Normal
World Density: DENSE
AI: 6 Opponents, Hard Difficulty
Also, I can't even load the game without crashing -- you're able to load it???
There were a bunch of World monsters roaming around as well as lairs and none of the AI players were eliminated at this stage of the game.
I started new games and can load those saves just fine -- this particular game I cannot load at all.
