I have a noobie question, I started my first patrol on 12/8/1941, heading to Midway then onto Boingo Straits (sure spelling is off). I always check to see how far the last way point is. The first time I checked it it was like 1358, then about an hour or 2 later I checked again, it was now 1398?

How can I travel towards to Midway and loose miles? Not sure how this happened. Has anyone else gotten this? I have RFB latest edtition, RSRD latest edition and patch for RFB.
