I have set in an init.sqf file
civilian setFriend [civilian, 0];
The idea here is to create criminal AI on the map while players can choose their roles.
The main issue: The civilian player can no longer pick up any weapons or ammo or backpacks, etc. from ground or from ammo/weapons boxes regardless of side.
This issue was already brought up in a previous post but closed for inactivity after more than 12 months. It has not been resolved.
