So I sank a 12000 cruiser,
few days later I see the same class cruiser sailing on it's own in same general direction.
Takes me a while to catch up and evade all the airplanes and destroyers.
I sink it by shooting it with two torps: one in the front ammo store, and one in the fuel tanks.
She sank shortly after...
but I did not get credit for it
just heads up so that others don't do the same mistake.
