Canon 60D switched from Raw to JPG after 10k Roll

I was out shooting today at a Local Airport for there Warrior War birds Air show in (Monroe NC)
Using my Canon 60D I had it set for RAW.  During the Shoot. I forgot to reset time due to DST ending and I made the change after taking a few shots.
During the event the camera rolled over the 10k shots.  Later I discovered that the Camera switched from RAW to Large JPG.  Has anyone had this to happen to them?  I will admit it could of been me changing settings by mistake.   But I can not reproduce until I shoot another 10k.

I saw similar issue reported by a 1D X user. It was a setting changed accidentally. Make sure you have the latest firmware and wait for another 10k shots to check
