Hi
Could you change npc will roam around hacking create and air drop? because I had tested a few npc types, and group of NPCs went to air cargo and they didn't attack players who approach hacking create and air drops.
It looks like so easy NPC event for getting items.
And I had tested with option "Forcibly immobilize an NPC": true, but NPCs had never move and never change direction, players killed just only with sniper rifle and players can get items.
