Great question. I did not get to finish my lunch, either.
Before I called you & interrupted your lunch, however, I would have reviewed what the error was (from the answer):
"Database cannot be reverted. Either the primary or the snapshot names are improperly specified, all other snapshots have not been dropped, or there are missing files."
That may have pointed me in the right direction. Then I would have done some research. Hopefully by then either I would have the solution or you would be back in the office; and you would have enjoyed your lunch uninterrupted.
P.S. It should be noted that I wasn't invited to lunch (I love Chipotle). Instead, I'm at the office wondering why the revert didn't work :crazy:. Upshot: I learned something very valuable that I will never forget...
