Kewl.
I was able to backup to the previous turn and continue playing...
BTW... you can provoke another CTD off in the far west. I think you will find a unit with a cavalry regiment and infantry battery by Ft. Gibson. In the save you have, this unit has been given orders to move to the north. Stop that movement and give them orders to attack (in the province he is in.. no movement)... there is a reb unit in the province right next to them who will attack him or perhaps is in the same place... don't remember. When the two came together for battle (on the next move from the save) it provoked a CTD three times in a row (always make it do it three times before I say anything).
Well, I was pretty into the game, and it was off in the west, so I just ordered the unit north for the next move. On that move (the save I sent you), he moved off and away from a CTD (I mean battle

), only to then encounter a second CTD on the same move in the mountains in the Eastern theater (the one that will occur when you play the save and is the subject of the thread).
Two for the price of one!
