I don't know Herr Kaleun(Alfman), but note it was an older version of SH3Commander, 3.2 was not installed at this time.
I already saw some mistakes in the preview version, one time I was killed in patrol but the patrol log said the same thing: captivity.
PS: now I must try a DID campaign and learn how to fire torpedoes manually because without it I still a pure newbie...I have begon a "Jochen Mohr campaign" onboard U-124 and I'll try to do it. So long mates, I don't know if I would come back home again....
