I had heard a little about the torpedo scandal before. I thought it was more about the switches/detonators.
I didn't know the game was modeled to that level of detail to make the torpedoes change with time.
So... I won't bother with anything that has <10 ft draft for a couple years, I guess.
Kinda bummed... I've been on patrol for over a month and this was the first real target (besides 2 destroyers that spotted me and harassed me all night), and it looked like an easy kill. I got 8 sampan kills so far though!
And I learned an important lesson: Just because a ship is going 5 kts when you launch, doesn't mean it'll keep going that slow once the fish are in the water. Note to self: lead slow-moving ships a little if they can go faster...
