Thanks THEBERBSTER
I got that and the new FX, tested them out this evening ha ha 4 dud torpedoes in a row against an oncoming destroyer and then 3 passed straight through him, managed to sin him with a lucky shot but evedentily got sunk by another destroyer that was far too far out to try a torp run , particularly seeing as my torp speed dial mysteriously disappeared after the first dud, sigh!
