Villagers float, fly, don't sleep in beds, freeze, disappear

Villagers are acting strange. At night, they sleep where ever they were standing, or fly out of buildings and float in the air. Other times they are in the bed, and then disappear. Durning the day, they freeze, are unresponsive to trades or even being pushed. (This seemed to the same with Golams and Wolves.  They also show green sparks every day, (so do random "jobs" and beds) even when nothing has changed. 

 

Also, cart travel is lagging something terrible.  Worse then I have ever seen it.
