Last night I hit a Passenger Liner with two fish and after about 20 minutes it quietly sank. Due to outside circumstances I had to reload the game from a point a few minutes after the torpedoes had hit the Liner. Second time around it did not sink and after a while managed to get back up to about seven knots and trailed after the convoy. Is there some kind of random factor in the damage control ? Because I was expecting it to sink I used all my remaining shots on other ships and the Liner got away
