I was just playing MultiPlayer with ParagonRenegade and an Epic space battle ensued. Two large stacks clashed together and I honestly thought he would win due to superior defense.
But I still won and barely suffered any damage. By GalCiv 2 standards I am pretty sure that would have been a pretty tight battle with him winning rather easily. We tried a few times and the result is repeatable. It seems the presence of a Lost defender in my fleet is to blame, but removing it still resulted in somewhat impressive results considering I had no defense.
Here is the SaveGame from Just before the battle. Is this normal from the Alpha point of view or is it a bug?
