Please help. I have one photo that missing from my library. This occurred while I was fussing with the film strip at the bottom of the Lightroom page. The photo is intact in the hard drive, but in Lightroom it is not picked up. Lightroom won't let me re-import it either. There are no flags indicating anything is missing. Interestingly, when I click on the folder, it says "214 out of 215 photos", acknowledging that a photo is missing. Is it somehow hidden?
Lightroom is saying you can't import it a second time, furthermore its not a good idea to do so.
