"Sitefinity/Licensing" 404 After 15.4 Upgrade

Good morning!

 

We just upgraded our development instance to 15.4.8621 but are now getting an error when we try to access the site. It's 404ing over a url "sitefinity/licensing" that does not need seem to exist in the the Solution, let alone on the server.

Does anyone know what might be causing this or how to fix it?
