Why did they pull the new Sharp reg AR600-52?

A few days ago u/imperator314 made a post about the new AR 600-52 being published on Army pubs. However, the regulation is now gone.

Is it regular practice for the DoD to publish regulations and then pull them like this, or is this likely a cause/effect of our new Command & Chief?
