Enemies besides slimes just sit there and shake violently and dont move or make sounds and i can walk through them. other players claim that they are walking just fine. It's been this way for a week now. i've reinstalled java, deleted %appdata%/.minecraft and still nothing
Right now they don't do damage and you can't do damage to them unless you drown them or such.
you misunderstand, they just sit where they spawn and shake, more like vibrate...
