It's frustrating that one can't set the time when the time compression should stop. For example, one time I saved the game and used the fastest time compression. At 17:05 hours I was attacked by Diablo. Since I saved at 14:00 hours, I needed to wait and wait and wait... 'till the time would have been ~16:55 hours, as I think that every group needs to get a car with soldiers to another group to attack it, no? (and I would have liked to kill the damn Diablo's before they made the attack) After some time I got nervous and started a new game :ranting:
...but I got a lesson from all this: never ever select the normal difficulty setting
