Thank you for the advice everyone. Still no luck though.
Weather is calm and type IIs only have a bow torpedo compartment I belive. Have tried to switch silient mode on and off, but no effect there.
I have every space in the torpedo compartment ocupied. Including the officer slot. all men above 2/3 energy, and the officer + 1 petty officer have torpedo qualification. I think that should be enough for reloading?
@Corsair: Please explain, I'm a bit daft.
