From standing on a base roof ect you can shoot the barrels and signs and they auto loot.  I have default radius set to .5 so this shouldnt be possible. People have learned they don't even have to leave their base to farm the roads.

Or you can disable the barrels and signs on "Loot Container Pickup Settings"

Didnt really want to disable barrels as that was one of the reasons I added the plugin, I enjoy playing the server as a non admin and loved the autoloot the most farming the roads.

Merged post

Or do you mean, once the items drop youhave to be in range and auto loot would still work?

Ok yeah that works! Thankyou!!
