DEck Gun Ammo

[Johnfb]

Hi All

I am in the middle of a patrol and put the crew up on deck in case of aircraft etc and have noticed that the deck gun crew are not loading the gun and that the ammo screen reads 0. When I try to fire the crew tell methey are out of ammo.
I have never shot the gun and in the weapons screen I can see 3 pics of ammo, 1000 shells or so for the flak and 2 screens of AP and something else which I assume is for the deck gun...problem is they wont load it...its on autoload.

Any ideas...or do they have to spot a target before they load


Thanks in advance
