I suspect this is due to my own practices, but I found that FFF has trouble detecting author changes if the url: identifier is missing.

Details:

I'd downloaded a oneshot from AO3. Since it was completed, I removed the url: identifier from the Calibre metadata and left just my custom ao3: identifier.

The author then orphaned the work.

I forgot I downloaded the fic and tried to redownload it. I didn't change the settings from the default "update EPUB if new chapters," but instead of skipping the story it instead downloaded a new one with author set to orphan_account (replace_metadata'd to 'Unknown').

I believe it'd been stated FFF had a third way to check for stories in-between checking for a url: identifier and using title/author match, so I am not sure if this is meant to happen.

It's probably a minor issue because most people probably just leave the url identifiers in there, but if it's worth looking into I've attached the duplicated ebooks + Calibre OPFs for investigation.
