Catalog & Finder pictures are different
I run LRC 9.4 on an iMac. Lately I came across by accident a photo in one of my folders in the Catalog that is different from the one it points to in the Finder - say you have a folder "Trip to london" and the photos in the folder have a sequential filename "London-1", "London-2" etc.
Looking at "London-2" I see Buckingham Palace but when I right-click it Show in Finder, the picture in the Finder is actually of Big Ben! The thing is that I would have taken both pictures but now they are one with the same filename!
Why does this happen?
How do i solve it to get both pictures?
How do I find other examples of this problem in a catalog of 70,000 photos?
