There is a "cleanup" process at the main Trader location on ALL of our servers. ALL items that are left on the ground within 100M of the main trader will be deleted every 20 minutes.

Items that are NOT affected by this process:
Vehicles/Helicopters
Inventory inside Vehicles/Helicopters
Inventory inside donation barrel
Animals alive or dead
Zombies alive or dead
Players (hopefully)

Any other items, including containers and their contents will be deleted. The cleanup process is set to run every 20 minutes and affects any item within 100 meters of the main trader. There are no warnings given. Do not leave anything on the ground that you care about. The purpose of this is to eliminate papers and other trash being left at the trader.
