I know your not meant to steal from the dead but....
When taking a backpack from a dead human player (medic/explosives expert in this instance) the backpack warps back and forth from myself to the dead player. When I return the backpack back to the dead player it becomes a duplcate.
I am unsure if the backpack is usable whilst its warping as the warping caused FPS drops so I returned it to the dead body. {F16984} {F16985}
