What's more interesting to me is that it seemed to reset some settings but keep others for both the E-M1iii and E-M1X; and then the settings that were kept vs. saved were not consistent between the two. Olympus definitely has some issues with their FW update process.FYI, this firmware update may reset all your settings!
Even though Olympus says that settings will be saved when updating the E-M5iii from version 1.2 to version 1.3, that's not what happened. I'm now on version 1.3 with factory settings. Fortunately I keep a written copy of all my settings, so it's just a half-hour of my life to set everything back to where it was.
