Now you tell us Sailor Steve, hehe!
I just ran into some of those unexpected minefields in the SE corner of England near the Southend ports and died a horrible death with all hands lost. (I was chasing some merchant shipping when I hit that minefield) New career for me, hehe.
You think you could mod a version of the nav map with pencil lines or something drawn on it that alerts you that there were reported minefields laid in the area (doesn't have to be precise for allied minefields, just vague enough to put us on alert) so we give those coastal areas a wider bearth.
What kind of intelligence did they have during the war on the location of allied minefields? I know they couldn't have known of all of them, like you stated about some of the German minefields. Other than other ships or subs being lost, did they just surmise where they should expect them to be and generally avoid certain approaches?
I guess I better open up that SCR file and start printing out some screenshots to avoid another untimely death by mines.
Great Sailor Steve, just great!
