I've had the same thing happen to me, and researching the problem with the RL torps found that one of the issues (along with the firing pin being bent) is the torps would circle if they missed (or they missed because they circled - who knows).

Anyway, I got lucky as I was at periscope depth when the torpedo missed the intended target and circled around me. I happend to have a destroyer overhead getting ready to drop depth charges and had the external camera on the sub looking up at the destroyer when I noticed this torpedo coming from behind me. It hit the destroyer slightly off angle, but hard enough to stop her cold and cripple her. Just lucky that day.
