V1.54 First to Fight multiplayer and 1-2 players get killed when helicopter takes off

[Hanzu]

Arma 2 Combined Operations
Harvest Red Campaign First to Fight mission played in multiplayer

There was 3 of us humans playing. I was the host and everytime I talked to the pilot and cut-scene fade to black started. Immediately after that always one and often two Razor Team members controlled by human players gets killed.

Both players were standing next to me. After cut-scene style fade to black screen the whole Razor Team is teleported to nearby helicopter. When I look other human controlled players I see them die and lean fowards once they are put to sit down looking like the helicopter seat is deadly and reason for their death.

I found this bug in V1.54 patch and reproduced it with V1.59 patch.

The only workaround for this bug is to tell human client players to disconnect before talking to helicopter pilot and they can join back already immediately after their Razor Team characters are sitting in helicopter and missions ends in some seconds when we are flying to next mission area.
