I have an issue in Lightroom v4. I have a number of collections which are now showing missing photos.
On trying to relink the pictures I navigate back to the original file path and on linking the original file then get an error message of "this file is already associated with another picture in the catalogue and each file can only be linked to one picture".
Trouble is, it is the same picture in every way and I don't have duplicates anywhere else.
The collections were created from pictures saved on an external drive just days ago and the file structure on the drive remains the same as at the time of importing the original files.
