so i created a superflat world with just lecterns. there was a village nearby. I saw some cats and they were just spinning for no reason! when i spawned more, most of the other ones kept spinning too! while i was messing around with the glitch i found more things spinning!

Created a superflat world, set down lecterns, mobs did not spin on top of the lecterns.
