After being killed by another player, my character's arms/hands were then always held up like a zombie. I found some information on it and found that the bug transferred to my friend when he allowed me to kill him. The zombie arms bug transfers to the player killed by the one affected by the bug. It is reported that it affects shield, shooting arrows, and the speed of eating food.
