Found another bug, at any time compression where the game disables the officer voice chat and you set a heading the U-boat will not turn to the heading. Once you slow down so you get crew voices again the heading dial works fine. Minor nuance considering!

Loving it so far, glad I had a tiny hand in it's creation

I'm still using the original BETA release so
