My torpedo's depth isn't the same as I set in the attack map.

Hi,


The title speaks for itself. I usually set the depth of the torpedo equal to the draft of the ship for maximum flooding possible and it works most of the time.
But as I snuck upon a large merchant today I fired a salvo of 3 torpedoes from 4km away and only 2 of them managed to go off and impact the ship. The
third one had a depth much deeper than the others which I noticed when I went to external camera mode. This is also the reason why I never use impact
and only magnetic, because it just doesn't work. I set the depth about half of the ship's draft and the torpedo doesn't dive or rise to the correct depth.
Is this a well-known bug? I am NOT using manual targeting.


Thanks in advance,
Mildly
