Here's a REALLY interesting development. So I figured I do Scapa tests with each of the four base NYGM files one at a time.
Install 2.5, same results. Able to sail up to the destroyer and give it a bronx cheer.
So I figure, try NYGM 2.0.
Success !! Multiple tests, the destroyer engages me at 3-4000. That's more like it.
Makes me wonder if something is wrong with my 2.5 file, but I got it from here at Subsim.
