Oh yeah, and the dud torpedoes. 8 in a row does sound really curious. Might be something wrong with your setup there. Maybe try taking dud torpedoes off and see if they function then?

However, historically 8 in a row has happened. Prien experienced that during the Norway campaign. In the end he had a few eels left, stumbled into a convoy and decided not to attack, since the torpedoes didn't work. Dönitz approved the decision, which kind of tells of the huge amount of frustration felt at the time.
