I just sense the Do'nuts had reloaded their battles in order to win. If I were you,I would ask the moderators to check for reloads and so on. To cite the 11 september broadcast. "One time time could be an accident, now this is two times, and that is no accident. This is not an accident, I repeat, this is not an accident."
Well, 19 out of 19 battles lost when they kept the save is beyond a pattern,I would actually consider foul play to be involved here. Call me a paranoiac or whatever politically correct jitter some sleazy demogamers like to flaunt in order to get a leg up on their honest counterparts, but I rather stick with probability science, my gut feeling, and my nose for cheaters.
I am now playing the Combat mission metacampaign, where there is no room for rule manipulation ("Team KISS"), no room for save reloads ("Team Doughnut") and no room for complaining on the game intent on Spirit of the Game ("Team MIA"). This is just my honest opinion. We were lucky to get an early settler, and this is how the various sides compensated that lead.
