1. Pitch a Big Military Tent.
2. Put stuff down on the floor inside of it.
3. Reboot the server.
4. Log back on and see what disappears and what doesn't.
5. Gas can is definitely affected. We left one inside the tent inventory, and another on the floor of the tent. After server reboot, the gas can in the tent inventory was still there, but the one on the floor of the tent had vanished.
