If that’s it, it feels a bit creepy that someone else has access behind the scenes but doesn’t show up in the user list. I’ll continue believing it’s a database glitch.
Spent my entire career working in the “Black Helicopter”, “Surveillance Drone”, network exploitation fields. (Some others). This type of thing is pretty low on my paranoid list.
The Users page should now appear as expected. I’m going to close this thread - if the problem reoccurs, go ahead and open a new ticket with Problems & Support. Thanks for letting us know about this!
