Added a very primitive way of making multiplayer work, it detects if the world is multiplayer, then it will check if each player is alive, then it will chase the last player it checks if they are alive, once they are dead, it will go down the list. If you are in single player, then it will just go after you without any other checks. The game might sometimes crash due to "Can't find the player I'm trying to target, so I'm going to crash instead of, I don't know, just not do anything"
