I have logged a tac case aswell but wondered if anyone had any suggestions,
have gone into system wide config>cleanup settings and known devices are set to 0 (unlimited) so shouldn't disappear https://wickedsick.tv/en/porn/1965266972/pornhub.com/popular/1/ .
I can see in the event viewer auto cleanup is at 2.30am in the morning but shouldn't clear known devices should it.
