Strange...
I just returned to Keil after my first patrol in a dugout canoe. I sank 3 merchants east of London and did not get credit in SH3 or SH Commander. I saw them go down and had the red "sunk" icon on my map view but no credit.
Any ideas?
EDIT: Nevermind. I added crew before my first patrol and I guess that is a no-no. Stupid stupid bugs.
