OK, thanks... I set the group to 100% spawn every 24 hours and parked myself just east of the "strait" there, and watched four groups in a row not have any trouble (got sunk twice). Generally, when a group spawns as you encountered, there is something "off" in the group's config somewhere, but I haven't found anything as of yet. I'm done with the look-see testing, and will "dive" into the text stuff further, and maybe spreadsheet the waypoint speeds all of the way, and look at a few other points in the file. The group is such that it has a 12 knot max, so if there is a waypoint somewhere in its journey that exceeds that speed, it can lead to trouble spawning "cleanly". My guess though is that there are too many "escorts", and escorts in the Silent Hunter games like to flit about the place, running into each other or their charges as they do their pirouettes and knuckles... I'll probably eliminate the 90 degree course changes, as that possibly contributes to what you had.
