When I start a Dogfight from the BDAc options menu, the battle starts and it automatically puts the pilots into Guard Mode, and they go to fight each other. They fire the vulcans at each other but it doesn't do damage. Sometimes I think I see some of the bullets go through the planes, but I might be mistaken. And yes in the menu I have bullet hits on. I always put one of each type of ammo box on my planes for just in case moments. When the bots run out of ammo, they still try to shoot their guns at each other, but sometimes they get a lock on the other planes and go into the rocket selection, but don't use them, no matter how far away they are from each other. I also tried .50 cal turrets, and those clearly hit, but still do nothing. Could I have maybe installed the wrong version of the mod, or just installed it wrong?
