I have Usio Maru ships in my game and really love their appearance. However I noticed something a little strange and maybe I am missing something. I ran a mission and my whole air arm blasted away at one Maru ship. No damage occured even though it was hit with bombs/rockets/strafing. When I purposely ran my plane into the ship, a bomb damage crater opened and was displayed. Has my setup gone kooky, or has anyone else had this? I remmeber awhile back that someone mentioned the invincibility of these ships but how, and was, it addressed?
