When running, in creative, and hitting the ground with a sword(doesn't mater which one) the player gets teleported back a little. It's not just lag because the rest of the world isn't effected(I made a zombie run after a villager and did the bug and they weren't effected). It might have something to do with not being able to break blocks with swords. I hope this will be fixed soon.
