Hi, friends.
I´m playing with the 1.13b patch, I as CSA vs the IA. I had a battle at Norfolf. The federals disembarked on Hood. Hood, inconceivablely retreated after the first day of battle, and it was the result:

I lost the battle, losing the half of Union casualties, destroying one full federal division and losing 4 NM points!!!
O.K. with the owner of terrain win the battle, but I think that nobody must lose NM because my casualties were minimum.
