You can only get a 90-AOB 0-gyro "dud" in SH3 by setting the depth wrong and having it bounce off the underside of the hull. Unlike IRL, the game engine guarantees a detonation when a torp strikes a hull at a normal angle (i.e. horizontally perpendicular and vertically perpendicular).

Well this one did, I watched it on event camera. Fired from 900m the thing actually deflected downwards, clipped THROUGH the edge of the hull before vanishing down into the depths. Definite :o moment!

Sure do :know:

Sorted my problems out now,everything is in order again (check my 'optimum firing angles' post)

:D
