Problem with an apc transport mission

[WurschtBanane 11]

Hi. When my btr-80a gets to a position he activates a trigger which makes all passengers jump out:

(units group unit1) allowGetIn false;

Unit1 is part of the passenger grouo, the btr80a driver gunner and commander are in an own group.

The problem: When an area has been cleared the troops are supposed to get back into the btr and let them get driven to the next target. (units group unit1) allowGetIn false;

Sometimes they all get in, sometimes 2 or so stay outside next to it and never get in which prevents the btr from driving. What do i do wrong?

//EDIT: It apoears that setting the passenger squads awareness mode to careless fixes the problem. But then they dont even shoot back. I could change the mode with waypoints, but that makes them not get back in at all.
