I have had some interesting "incidents" as well. Using TMO last night I got lucky and came across two fleet carriers lightly escorted. And by lightly I mean only one cruiser. 15m/s winds and rough seas, I got into position and fired all 6 of my torpedos at the three of them. Just before the fish hit the cruiser, I got a ship sunk icon, but no credit. The other 4 were right on target hitting both carriers. one was a dud, and the other two detonated. I followed the carriers for a while trying to reload since their speed had dropped. As I was preparing another salvo on the two damaged flat tops, they sank.
This just left me scratching my head considering that I usually have to put at least four torps into one carrier to sink it, and had the one sink from one torpedo strike. I guess TMO models rough seas and some of the sinking mechanics...
