The game reverts to the standard loadout (in January of whatever year you happen to be playing in) regardless of the fact that you've changed torpedo types just before going out. I found this out in another career which started in October 1940.
This is off topic but I can't seem to find the information; when I've started careers on Sept. 1st 1940 from St. Nazaire the base
does appear on the map. Almost immediately after I leave on patrol, it mysteriously disappears!

I find that I have to cheat (hit Return to Base) when I'm out of torpedos as I can't remember the way home.

I've checked other threads re: rebasing & St. Nazaire not being on the map until September 20th (there abouts) and found that my cfg file matches up with the suggested solution for that bug. Is there any way to fix the disappearing base bug?
Thanks again for all the help.
