Unattended superhub factory restore?

Howdy all,
Just curious if anyone has run into a situation where your superhub restored itself to factory settings w/o user input?

I came home last night to discover my superhub reverted to factory settings, so my SSID, passwords, and port forwarding rules were all wiped. Granted, it was simple to revert back but I'm just curious why it did it? I'm going on the assumption that some sort of firmware update was triggered, but it's a bit annoying/worrying that it did it on it's own.

Thanks!

It won't be new firmware as that isn't scheduled until May/June. Probably yet another bug
