i ran into a problem that my recon mission don't get accomplished. I was given a task to photograph all ships in a Ishinomaki harbor. I arrived there in heavy fog at night, so i waited at periscope depth there untill the fog was gone. Had no sonar contacts going out or into the harbor as i waited for good visual. I raised my scope, encountered only two ships there (one Subchaser and one Gunboat), i took pictures of them both but the recon task is still showing incomplete
I also used the free camera to see if i missed any ships, but no - there are only this two ships in that harbor docked
