Sometimes when i put the weapon in my hand to ground i can't pick up anything from the ground or my inventory to my hands by no means, i tried dragging it from inventory and clicking "take" from right click menu. One time it fixed itself after blowing a few (actually quite a few) punches to the air. And when i log off and immediately log in to the same server, the weapon i put on the ground is in my hands (except one time, it went missing, not on the ground, not in my hands, just disappeared into thin air). Sometimes the glitch is fixed after that, but most of the time it doesn't, looks like a server issue. Never tried to log in to another server immediately. I quit, log back in to same server, see the weapon is still in my hands and then i switch to another server. %90 of the time problem doesn't persist on the other server. It is annoying because you don't know when will it happen, it can happen during a combat, or while you are trying to loot a dangerous area and if you get caught without a weapon in your hands this glitch will definitely prevent you from drawing another one without relog. And cause you to die, be it another player or just a couple of zombies. So you just have to log off and don't come back to that server for a while, because you don't know if and when it will happen again.
