Bug: You can duplicate items that are picked up into hand. I have only seen this happen and have never reproduced it myself because I am not about that type of game playing. The other player who taught me this said you can do this with any item that can be picked up into hands. When he did it in front of me he had an M4 on his back and there was another one on the ground. He picked the one on the ground up into his hands and then he crouched. He raised his weapon with spacebar and then logged out. When he logged out the weapon dropped to the ground while his character sat down, got back up in a standing position and went prone before sitting back down. I was able to pick up the weapon and he logged back in and when he eventually got back in he still had the weapon in his hand. He told me if you aim down the sites instead of raising the gun, it will just delete the item in hands. When he logged out, his character model stayed there for a very long time. Right until he logged back in which he had to wait for a log in timer when he did.
