Torpedo Shortage?

[Folducker]

I am still having problems with Torpedoes, or the lack of. On my fourth mission with an S boat. Been to Tokyo to photograph the anchorage (You don't want to try to do this at noon, as you will be spotted and sunk trying to get out) and made it back to Pearl OK. When I went on the Photographic mission, I was only given 3 Torpedoes which I didn't use. Next mission is back to Japan to "engage shipping" Only problem is, I am only issued 4 Torpedoes. Do they really want me to go all the way to Japan with only 4? Is there a configuration setting I can modify to get a full load? I don't know if I have a problem with the game or not. I did have a crash when playing single missions. Previously I came back from a patrol with empty tubes, was re-assigned another patrol to Japan, Went all the way, set up to bag some ships in a medium size convoy only to find out when I brought up the TDC that I didn't have ANY Torpedoes. I am at a loss as to what's going on.
Thanks
