The Camera_servo guardian went to wait_for_cameras, but had an error because of a typo in self.failure vs. self.Failure (it cares about capitalization).  I capitalized the incorrect version, selected a different state, and reloaded.  Reminder that I had to jump to another state so that it would load and run through the main part of Wait_for_cameras to pick up that new variable name.  Seems fine now.
