first off, am i correct in thinking that the join grpnull command makes it impossible for a loon to rejoin any other group afterwards? that seems to be what's happening here...
the scenario:
two civvies chatting, both separate.
one spots a friend in the distance, and the [two civvies] join the friend.
they saunter over to a meeting point, and a car comes to pick up the friend but not the civvies.
at this point the civvies then leave (join grpnull) the friend.
here's where my problem arises.
i now want the first civvy to join the second civvy and the two of them get in a separate transport. i realise they don't need to be joined to accomplish this, but it seems tidier - requires instructions just for the civvy who leads.
once in their car i want them to re-join the friend (who by now is in the car which came to pick him up) and follow him in their own transport.
everything works except the joining of groups after the grpnull command. they just sit there.
i could waypoint all this for the units separately but that's going to be a mess.
any ideas?
