Frequently when playing through a tournament in single player, the game will lock up when loading the map. It will show the sunray icon, and instead of pulsing and then loading the map, it will stay lit and the game will be frozen. Task manager says the game is using 25% of the cpu during this time, but it never finishes. You have to ctrl-alt-del and end the process.
Fortunately it saves your progress, so it isn't a huge deal, you just have to end the process and start the game again and it will work fine. It happens 1-2 times per 8 game tournament.
Just wanted to report it so that it hopefully gets fixed.
