Lost master files in Aperture
I recently lost about a dozen or more master files. I do not mess with the file structure. All of the lost masters were uploaded to both facebook and picasa using Aperture's upload utilities. I was able to semi-restore the files by dragging the preview files outside of Aperture and re-importing them, but as a "professional" app I should not have to worry about losing my pics when doing basic functions like this. Any suggestions on cause and/or avoidance?
