Since I've tried to fix multiple quests by myself (a lot of VIP5 quests are broken), I've had a problem with Vehicle-NPC's which get stuck when get attacked.
When the Vehicle get attacked, its position seems to get stuck on the server.
The client can move in the world but nothing is reacting to it and if unboarded or relogin the player respawns on the last attacked position.
The simple but (for me) hard to find fix was to add the unit_flag 131072 to the vehicle NPC.
It seems that the Vehicle is attacking hostiles by itself and then get stuck. Flag 131072 will prevent this.
It's not much, but it took me a long time to find out, so I'll post it here.
