After installing the .99 patch over my .983 install, I started a game, customized a race and sovereign, and got to the "Creating World" screen. While that was loading, I hit control-tab. Nothing happened for a few seconds, then my starting location on the map was shown, and the map faded back to show the Chat/Friends/Achievements menu. I clicked on Achievements and the game crashed (with the Windows "Fallen Enchantress has stopped working" message.
No dump file was created. Debug.err is here.
