I am going back to version 1.0X.010. I liked the first Beta 1.1 (wish I could still run that) but the second one is loaded with very severe problems. First of all, I am averaging more than one crash-to-desktop per hour. Secondly, it is riddled with errors --- Social Production indicates it is being moved over to Military Production, but it is really being wasted (so worse than original). If you do ^N in campaign mission, it restarts you, but with random settings. At some point after you load a saved game, it will tell you that all your units are outside their range. At that point, any other game you load will have the same problem. Fortunately, ending the program and restarting fixes that problem.
At any rate, until Stardock gets there act together on this one, stick with the first beta if you haven't already upgraded!
