I have a tent. Tent has not been stolen from by other players. Tent is on a server with persistence enabled
Basically I put an M4 in the tent with all the attatchments.
After a server restart all attatchments on the M4 vanished except for the Magazine and RIS handguard.
I equipped the gun and confirmed those parts had despawned from the weapon. I as even able to add spare partS I had.
After this I placed that m4 back into the tent.
I returned the next day and now there is the same M4 devoid of attatchments in the tent BUT 2 more M4s also spawned on the ground inside the tent. So now there are three copies of the M4 devoid of attatchments .
Additionally the hunting backpack I had in the same tent also duplicated itself on the ground inside the tent.
I confirmed that these items were still in the tent .
