1 - spawn units on server
2 - set owner to HC
3 - assign waypoints on server (command is global args and effects)
4 - watch them do nothing. I even had problems getting them to shoot me if I shoot a couple of them (but that might be separate issue to raise later)
Play the attached demo mission
(I called my HC profile "hc1")
The units should get transferred to HC and then move to "mkr1", "mkr2" and "mkr3"
The mission has some sideChat sent to you by server so you can see what's going on.
