a little confused....
 

British supplies,
how the hell do u complete it?
ive sunk over 184000 tons off the coats of Britain, and still nothing.
ive finished "sink 50k tons off the coast of britain".......and upon "ending patrol" i talk to the dude in the sub pen and he gives me the exact same briefing as last time. am i missing something?? or is it bugged?

Have targets sunk all been with'in the area that is marked on the map?

yup i sent a message to bdu coz i know that i reached to correct tonnage. Bdu simply said "ok come back to port or contine to patrol a grid of your choice. i had no torps left so i went back to port clicked on end patrol, went to the dude for more orders and got the exact same one as i just completed :S same briefing and everything!
