I'll stick around a bit longer, maybe there is a certain ship that triggers it or something lol.

as far as your mission success is concerned, there are basically two main objectives:
a patrol objective has one requirements: stay in a certain area for a certain number of days. the trick is to know what the patrol radius is from the center point. this is not always shared in a forthright manner. i am in the habit of checking the objective MIS file so that i know for sure.
a sink object has two requirements. enter a certain area with a defined radius AND sink a certain tonnage of ships. the patrol radius will automatically trigger a message when you enter it, unlike the patrol objective above. the tonnage requirement is rarely publicized. don't ask me why. nominal tonnage is 4000, 5000, or 10000 tons. here again, i am in the habit of checking the objective MIS file prior to shoving off.

i hope this helps. if not, let me know.
good luck.
