the distance adjustment for the MK 45 Gun is useless. it always fires at the same distance, no matter what value it's set to.
(edit: i figured that one out. when you set the weapon firemode to "full-auto" the distance adjustment works with the gun. the other firemodes fail with the distance adjustment).
and the artillery computer dosen't work as it should. everything works, like the range settings, the target coordinates, the eta, etc. but when you hit "fire" , the projectile just flies a short distance, like manually fired.
though the computer indicates its flightpath, but the projectile never reaches the target.
(edit: i figured that one out, too. in the gunner's view you have to zoom in until a blue map appears. then open the artillery computer and it'll do.)
and when walking on deck, there are some spots, where you fall through the floor (upper and lower part of stern). impossible to land and get out of the chopper, without falling through the floor. or when getting out as driver of the ship you might fall through the floor at stern, when trying to get down to the helipad.
(edit: on these parts of the floor, you are unable to walk:
and the ai doesn't executes waypoints properly. it pushes the throttle, then stops, then forward and off again, and so on.
and the stern light is flickering.
when landing with a chopper then get in the ship as driver and drive. after some time the chopper will explode.
and landing, by the way only works, when no one is abord the ship. otherwise it'll chrash immediately.
(edit: these ladders don't work:
