I think you misinterpreted the symptoms. If an update rollback showed all your files again then they were there all along.
If you want to find an explanation, I suggest creating a thread of your own in which you describe each observable symptom and key facts about your setup such as the nature of the user accounts on the computer & the locations of the user files.
Naturally, you might not be particularly interested unless it happens again.
