- In order to change the behavior of a unit currently following a string of waypoints, it is not enough to use deleteWaypoint. The path of the unit is calculated by the waypoints present at start, and the unit will continue according to the original waypoints even if you delete them by using this command. To achieve the wanted effect, you should rather use setWPPos to the units current position (thereby stopping the unit), and (after a small delay) use deleteWaypoint to remove the waypoints.

- Another (more foolproof) method to avoid the problem of non-deleteable waypoints is to introduce another group (createGroup) and join all units of the present group. A new group will start without any preset waypoints so you can start setting new WPs all over again. Example: Old group is "_combatGroup", new group is "_combatGroup2" _combatGroup2 = createGroup EAST; {[_x] joinSilent _combatGroup2} forEach (units _combatGroup); _combatGroup2 addWaypoint [getPos player, 25];

- When you want to remove all waypoints, do NOT iterate over waypoints _group while trying to delete them (an array is by reference!). Instead use an approach like this: while {(count (waypoints _group)) > 0} do { deleteWaypoint ((waypoints _group) select 0); };
