thatīs a weird problem.. i only solved it if I did the waypoints almost in that way that the escorts should run aground! try to use a route along the upper coast before turning left towards bay of biscay!

That seems to do the trick by running the waypoints to the extreme right--it works but it seems the escort is still fighting itself to turn left and beach itself--almost as if the lighthouse there is a huge magnet-oh well that it got it working though. thks han solo
