Context: I did a database restore after running into a catastrophic failure when I mistakenly deleted the postgres folder after a power outage.
Issue: The backup restore was successful, but all images that I made custom dates for are not showing up. This is what the files look like in the upload/library/admin/DATE/... directory (image123.jpg, image123.jpg.xmp). Only files with changed dates with .xmp companion files are not showing up.
