It was actually the .LND file that I had to open to move the "dot" for Kiel - but I did it and then changed the Flotilla.cfg to match the new lat/long and it worked!
Also, it turned out that there was another uboat between mine and the side of the pen... don't know why I never noticed it, lol, I guess I always just pulled straight out of the pen while charting a course in the Navmap view and never had a better look around outside.
I only started patrols from there to test out stuff for the Type II and that's how I noticed the damage warnings in the first place... apparently the starting point put me so close to the other boat that we were rubbing love handles when I passed by, which wasn't obvious on the surface when you couldn't see the full curve of the tanks, but that must have been what it was.
Anyway I moved the starting point a little further out from the other boat and tweaked the starting heading a few degrees so now it should be a straight shot out of the pen with no inappropriate fondling of another kaleun's uboat.
Thanks again, guys, this was one of those niggling little things that always bothered me and now it's gone.
