If you go and create a new world all Blueprints will be set to "others" and "enemy usable" + they will lose their owner.
Created permission test in world0
{F184}
then created new world and this happened
{F186}
The DEFAULT_BLUEPRINT_ENEMY_USE = false from the server.cfg has no effect on this.
Putting this on high since it can break worlds if all titan blueprints are auto spawnable
