In my world before I signed up for beta again. The villagers are glitched. Some how a villager is outside looking the same direction as the one in the house. But its not real cant hurt him he floats when I remove blocks. Also the villager in the house moved opened a door but on my screen he was in the same spot. Found a spider doing this too. Hissing I try to hit it doesn't do anything. Then the spider disappeared. Started a new world same thing with other mobs sheep. The lag is so bad..Its not playable at all. Too many bugs.
