My touchscreen rebooted at 12:49 am this morning

Was there some type of an update? I received an email saying that system was armed night via touchscreen at 12:51 am and it was already armed night via automation at a preset time. I have a camera in the same room as the touchscreen so I zoomed in to view the camera and advanced the time. It looks like the touchscreen rebooted at about 12:49 am. So confusing and concerning when you get emails saying that security system was armed night via touchscreen when you know it already was armed night and you read them early in the morning when you are still half asleep.
