[Torvald Von Mansee]

I got this bug: I got into perfect firing position to nail a Medium Cargo ship, but my crew refuses to acknowledge its existence. I tell my sonar man to track it, and he says "No sound contact!". I have RAMMED this ship, and my watch crew never says: "Ship spotted!" If I sink it, it doesn't appear in my log nor does my Navigator say: "She's going down!". Anyone know why this is happening?

Serious answers only, please.
