I'm loving this mod so far: Excellent job! Single bug I've noticed: I key takes you to damage control, not torpedo inventory page. Everything else seems to be mapped correctly and the only other thing that was bothering me went away when I unchecked Environmental Effects. I'll let you know what else I run into with USS Whale.
Torpedobait: The numbers you're looking for are in Data\Submarine\NSS_whichever\NSS_whichever.upc. It's right near the top: in the first paragraph you'll see lines for MaxPettyOfficers= and MaxOfficers=. I changed those to 59 and 21 for the Gato. I recommend copying the UPC files into another mod folder, changing them there, then activating that over top of FOTRSU but that's just my not wanting to muck about in the original.
Cheers!
