I have had problems like this, some times when leaving a harbour if the first waypoint is to close it misses it and circles to try get to it. Try moving first waypoint further out and making the tolerance to 1nm or more if needed. I had the same problem when i was working on one of your scenarios Fish. Remeber the one that i moved the FFG out of the harbour because it kept hitting it when it started to move. Well i could get it out of the harbour with using some waypoint very close to starting position but when it came out it would circle back as it was missing the waypoints. When i took it out of harbour and moved the waypoints farther out it was ok.
btw, dont try setting out a curve of waypoints close together to make it turn once it comes out. Just use one at point u want it to change course then another farther out at least 3nm on the cource u want it to take. If they close together then u get same circling problem even with toleranc set to like 10nm
