I tested making a simple heli dropping of troops and leaving mission. Problem for me is that the chopper doesnt land properly but hovers around 8m off the ground and since i syncronized the transportunload wp with the "getout" wp of the soldiers it FORCES the soldiers out at this point before the heli turns around and heads home. This causes the soldiers to recieve injuries upon touchdown.
Tried this multiple times and it is very easy to replicate
Also tried this using script to force the chopper to go lower but it still wants to unload the soldiers in mid air.
