Thanks for the replies.
It's Oct 10, 1939. When I selected the british coastal orders, I left my base from Kiel and had been patrolling the various ordered sectors until I received a radio message saying that I'd been reassigned to Wilhemshaven. After I received no more orders to patrol certain sectors, I returned to Wilhelmshaven, selected the anchor and ended mission. I'm a bit confused now
edit: Since sober said (unless Imisunderstood) that there is no maximum tonnage bar to worry about with this mod, I simply returned to base, though british coast is still available, as well as breaking fortress, and another mission as well
edit2: love your tutorial thread btw, theberbster!
