Saw your post on the gyro problem.. I have seen this several times on my last patrol, I think it first appeared around patch 7..
>>>Since one of the recent patches I've had an issue with the gyro settling in the wrong place, some of the time, so that the torpedo course line is clearly in error. I know where it should be based on target range and speed, and sometimes it stabilizes well off the correct course.
Hope you made a bug report!
