I recently upgraded to 1.02. Everything is going fine, fewer crashes than before. I saw the new regional options, wasn't expecting those.
Playing the full campaign as the Confederacy, in early September 1862, a unit appears in Chattanooga that displays an ability with a red "?" in a white circle, and says something about "erroneous ability" and other things. I've posted the screenshot. I can move the unit, but I haven't tried to fight with it yet. Thinking it might sit out the war quietly somewhere so it doesn't accidentally crash my game.
On an unrelated note, I saw the "contrabands" units in Baltimore with Burnside, but I took him and them out when I overran Baltimore.
