The problem is not that the game is crashing when a turret hits the Aten/Mentu. The problem is the game crashes when the Aten/Mentu tries to fire it's regular primary/secondary weapons (the kind fighters, bombers, etc. use) and discovers it does not have any. The normal Aten/Mentu models do not have gun points and missile points. Only turrets. If you want to use it with a fighter/bomber flag you have to edit the model and give it at least one gun point and one missile point. Then edit the table file, adding in regular primary & secondary weapon data from another fighter. The ship seems to use it's turrets with both the fighter and bomber flags, but as it's not a cap ship what turrets it can equip is limited. (Unless you edit your weapons table.)
