Question that I was quietly in my minecraft world with friends, on a free server host and it was night, then out of nowhere I started receiving constant attacks as if it were a zombie but x5 times faster and they did not stop , I let myself be killed and said "PesteNegrinia (my minecraft username) was killed by Spider" and I was honestly very confused. The hitboxes, and nothing, I was with 3 friends and I know if it is one of them, the error happened 2 times in total and it happened to me as much as in multiplayer as in singleplayer, the hits took away 1 and a half hearts but they were constant and it is very annoying going out to explore and being killed by an invisible creature called "spider" when in reality I didn't have a hitbox, I hit it with my sword and nothing happened
