Today I opened up my Lightroom only to find all of my photos from 2015 GONE. It told me it updated to "lightroom mobile" and then when I opened Lightroom up all of the photos I've imported from 2015 aren't anywhere in the catalog. I was working on a recent shoot and all of the edited photos are gone. Does anyone know what happened or where they could have possibly gone? My photos were recently backed up as well.
