Just picked this game back up again after several months working on other projects. I started playing the July scenario as the Yanks. On the first turn, I moved McDowell's army into Manassas for the ritual defeat. I was duly defeated, but my units didn't fall back. So I set him to move back into Fairfax, put him on "retreat if engaged" and 'evade combat". That turn, another battle. Did the same thing next turn. Same result. Rinse and repeat. Now it's November, and the Rebs are still kicking their favorite punching bag around. What's wrong?
I can't imagine that this is WAD. Another reason the system should just retreat defeated forces and lock them. Presumably something has been done in a recent version to screw up retreats even worse than before.
