Do you know of anything else missing? If it was a "code" error, like in a Drupal site or something it would likely delete other stuff. Most U.S. government websites are modernized during the Obama administration or newer. This stuff doesn't happen due to code.

There have been no changes to the Constitution that would have required them messing around with it at all. It's a static document except when there are amendments, and the most recent amendment was in 1992.

It's clearly bullshit. I can imagine the page disappearing entirely due to a coding issue, but the deletions were precise and clearly intentional. To what end, I can only imagine.
