The Creaking "slides" on the ground when not aggro towards the player

To Reproduce:

1. Spawn a Creaking.
2. Go to spectator mode or go to creative and press F5 twice, and watch the Creaking move behind your characters back.
3. Watch the Creaking, you can notice it moving slightly and it's legs moving a little.

Expectations:

The Creaking would either not move at all, or walk normally. (Though this could be intentional)
