Reloaded a save game...ships are undamaged?!?

[Kapitan Franz-Josef Lemml]

I saved the game right in the middle of attacking a bunch of ships that were docked. I had struck 4 ships and they were damaged and on fire, but none were sunk. I later reloaded the game and I am out of torpedoes...but the ships are all in perfect shape with all hit points and not on fire! What gives?!
