Good photo vanished from the library, and Lightroom won't let me import it again.
This started in Lightroom Classic 4, so I decided for many reasons to move to the newest Lightroom CC via subscription and the problem persists!
It's a photo I've processed a bit, then it vanished from the library list.
It's still on the hard drive, nothing wrong with it.
I tried to "import in place" but nothing showed on the list.
I ended up manually copying the file to a temporary place and importing it from there with the "move photo to your folder" option, which worked fine.
Now I have one copy in Lightroom : DSC_5762-2.NEF and on the hard drive I also have DSC_5762.NEF.
Note - I do not have "don't import suspected copies" enabled. Any ideas? I wonder how many other photos are invisible in my Lightroom main folder?
