Ok now i take it back, everything is not fine,

. Now i have apparently lost my torpedo wakes. this is very bad. I tried using torps without it, but seeing how i'm still trying to master the manual targeting it's useful to have them so i can make corrections when i reload an encounter after I bollocks it up (yes gentlemen, my training wheels are still on, it's only been twenty days). is this another noted effect of modifying a save file?
