New theory. Reading this:

It says
"Western Approaches 20/03/41 - 01/12/41
Flotilla 6th
Transfer from 2nd flotilla Kiel 20-03-1941 with new boat."
Am I supposed to start the campaign in Kiel? Because that would make a lot more sense. For me it simply started in my last base in Lorient though.
I'm all out of ideas on how to fix this though...
Sigh, spent the last two days just trying to solve this, would've preferred playing the game.
