Forgive me if this is a known fix I just missed in the database.
Darktable / Lightroom won’t open the images in the newest few directories of files on my hard drive, and this is not an obvious issue of filter by date. I don’t know if this is a thing like having too many (several thousand) images previously opened, or a bug, or me being an idiot.
If I say “Import Folder” for the last two or three directories of NEF+JPG, nothing happens (“There are not images in this collection”). If I go to older folders, the images import fine. (I have a screen shot but don’t see an obvious “inset image” here, sorry.)
Anyway, any thoughts? I would be happy to add more details if needed.
