No its a serious bug cuz I really he had such a good bow and a stupid wither skeleton killed him while blocking and I didn't duplicate from that

@Progamer How long was he blocking before the wither skeleton hit him?

He was literally holding the button which you can block with the shield he was holding it and still somehow killed!
