weapons when dropped on the ground and picked up does not get removed from the ground to the inventory properly there is some kind of delay / sync problem that updates that the item is in the inventory, my friend can remove the bullets from the gun and it will get removed from the first guy that picked it up previously wich causes problem in general, maybe even dissapear or get bugged is not confirmed but the first one is. I dont know wich other items this appear on could be a coding issue in general for all items.
