My Lightroom CC (osx) has suddenly lost hundreds of files at once. They don't show as missing (with exclamation mark), and synchronization won't help. Even re-importin is not helping, because the file window won't show the files.
The only place I can see the missing files, is in Finder. How on earth I can solve this problem?
Edit: I just tried to import more photos, and noticed Lightroom discards photos which may look similar!! I DO NOT want this to happen, what should I do??
