I'm playing as Indonesia. The game crashes every time I either 1) Discover Kathmandu or 2) just wait about 3 turns. I can halt all units, do only my basic building and it will still crash. I have a missionary that's out in the ocean heading to one of my farthest cities (built to use the spice islander UA). If you open the game you see that if he heads west he runs into Kathmandu and the game shuts down immediately. If he does nothing but sit still it will still crash, it just isn't as immediate. Computer is a laptop, AMD10 Quad-Core with dedicated video memory for games and it runs the game great. Don't know what happened or why.
