I am trying to make a trigger so that if the player(a West Soldier) is too far from the leader(a Russian) , he is no longer part of the group. So I used:
Condition: Player distance RussianGuy > 10
Activation: Player setcaptive false; Player join grpnull
But there is something wrong with the "player join grpnull" - the player isn't "unjoined" from the group (and then shot).
