I have made Mission with a y-32 VTOL taking off from an airfield far away from combat. This plane has 2 groups set to safe in it: One with the pilot and the co-pilot and the other one only filled para troopers sitting in the cargo room. But now when I start the mission the para trooper leader orders 8 of them to leave the plane and then orders 3 of them to get back in again (the plane has taken off already) leaving 5 outside. Something similair occurd in my mission with filled up trucks driving in a convoy. Is this a known issue or is it because the vehicle is fully loaded and therefor trying to get rid of some passengers :). I appreciate any help. Nico
