I have a game (insane galaxy), have included all the major races and allowed minor races. Several hundred turns in I've gotten a fatal error that reboots my machine (blue screen of death) in Win 8.1. Game is saved, but again the upload size is 32meg. This occurred twice in the game (reloaded after first reboot) and the fatal error occurred again w/in a few turns of the first crash. Will upload sys specs, but it's a very new machine I'm running on (one month old), high-end gaming machine.
