Lost DNGs

Hey guys,

I was editing my short film and I exited Resolve to delete a few b-clips and when I entered Resolve again, a major clip that I didn't delete was missing! I went immediately to the Recycle Bin to see if I had deleted it by accident but it wasn't there. And I'm absolutely sure Windows didn't ask me to permanently delete anything.

I used a tool I have to recover lost files and I actually found the right directory but with wrong dngs in there.

Does anyone know what the hell happened?! Suggestions?

Thanks

One more weird thing. The same clip actually disappeared from my media pool... This never happened to me in Resolve...

The only idea I have is Operator Error.
