The option in TDW exe generic patcher disables an option to manually select target with binos and fire with deck gun on selected target. Instead of that deck gunners fire on the nearest target only and proceed to next only when the first one is destroyed.
I disabled
the deck gun crew fireing automatically when target is designated for attack with deck gun patch and the gun works as it should.Don't exactly know what this patch is supposed to do but i think it somehow brokes the deck gun.
Just to inform you and the others who may have the same problem.
