I have 2 XS cannons installed on a ship. They are both plugged into the Hovercraft Seat Controller as well as the small ammo container XS which contains Cannon Kinetic Ammo x1000. But when I autoconfigure and enter the seat, the cannons show 0/0 ammo on the HUD. How do I load the ammo? Or is it just a display error and I just need to use them first for the ammo to show correctly?
