Hmm. I'm already in another mission and trying hard. Already failed once to sink 100k tonns, as convoy escorts crippled me in a failed night attack and I had to go to base. Then I had to request the mission again. Does it mean that I have to sink all 100 thousand tonns in ONE patrol? And if so - does coming back to base only to resupply and then going back to see without docking count as one patrol? How did you gentlemen accomplish this?
What do the small iron crosses in the left corner of my map mean? Why didn't I get one for accomplishing the 50k mission? Did I miss something?
Getting answers to these 2 questions is a good start to understand SH5 interface.
