This occurred to me five days ago. My friend and I got on around 16:00 and played until 18:00 hours.
My friend continued playing and logged out at 20:00.
When I logged back in at 21:00, progress had been reset to 18:50. I checked the log and saw the backups had several hours (1-6) between them:
At 21:00 I continued playing, trying to restore our progress and I logged off at 22:00. I immediately closed out Minecraft completely, restarted the game, and logged back in and the world had again reset to 18:50.

I turned off the filter for the profanity moderation in minecraft.net and it seems to be backing up again. Is there any chance that was the cause?
