Vybor military base, and possible other locations. Bags, and other items can disappear after a # of minutes.

I watched my high cap vests disappear 1 by one. I had 2 then re spawn latter on in the barracks at vybor military base with no items in them.

I carried my medical items in one, and ammo in the other. Both decided to go poof after a length of time.

Yet my items I threw onto the ground stayed.

Yet my blue backpack stayed.

Items left in the field can go poof as well its a random thing with most other items but when it comes to these high cap vests they tend to go poof after 10+ minutes.

I don't know if it was designed this way or not.
