Fall of the rising sun, no map contacts

[Raven79]

You'll get only a few infos from command on where to find convoys n such. If you stay in an area longer and report in once a day, you'll eventually get more reports of movements there. Yet, you don't need to wait for them, I never do, just cruise around and do listening dives once in a while. You'll find much more than your map shows you.
