Eccentricities of the ME

[Bahger]

So I plotted a convoy that had to go north, reach an objective, hold until a trigger fired, and then turn round, drive back south along the same route, passing its starting point, and go further south to its final waypoint. On five successive playtests, the convoy (Blue HMMVWs) did a U-turn at its start point and went south. NOT user error, I checked every WP, every WP order and every trigger. Only when I eliminated all WPs after the convoy holds at the outbound point in its two-way journey, did the vehicles head in the right direction from the start. Maybe when I replot its inbound route -- whch is not mission-essential, just good for realism's sake -- it will behave, otherwise I'll leave it as is, nobody will notice. I wonder what happened, it's the most eccentric AI behavior I have yet observed in the ME.
