Hello (ou bonjour plutot)

I really wonder how all of this works. I tried it for such a tim now. I selected a base area ( beautiful factory north of our biggest favourite city) and i gave a place to put weapons, food, bla bla bla.
I was happy to see they began to farm and forage or cut the trees but the loot in the factory ??? Even if there are many items on the floor, they absolutly not take them to put them in the different storage points i suggested them. How to do that then ? Because at least, i would love them to take the stuff i collect and quickly put on the floor and dispatch it in the different zones. That could be really useful

(Also, some orders are strange like patrol or guard. If there is a guard area, i supposed they would travel around and kill anyone coming that way, but in fact, they just don t move.
Same with explore. I could suppose they would go and explore and scavenge in houses close. But... no)

Could you explain me better ?

Thanks a lot :)
