In Lightroom, i have a file that is showing up in the library under "Error Images" and "Missing files". It seems that I have somehow deleted the file from the file system outside of Lightroom. Obviously Lightroom still has this file cached somewhere, as I can see the preview of the photo, zoom, in, etc. But i can't edit it or export the file. This version is good enough for what I need it for. is there any way to recover this cached version?
