[Solved] Selph scraper completes without actually doing anything

EDIT:
I discovered the cause as I was writing this post, I thought I should leave it in case someone else comes across the same issue.

The SSelph scraper does not work if you place roms in subfolders. In my case I had something like roms/nes/collection1/game.nes, when it should be roms/nes/game.nes.

If you still want to use subfolders, you should be able to direct the scraper to your roms and edit the parameters manually:
/opt/retropie/supplementary/scraper/scraper --rom_dir ~/RetroPie/roms/nes/subfolder1/ --workers 4 [insert params here].
The additional params would need to point to the system gamelists and image folders, some examples of what these params should be is here

Hi There!

I've been trying to get the Steven Selph scraper to work, but haven't had any luck. Here are the details:

• I installed Retropie on top of the latest Raspian (stretch 9) using a Raspberry Pi 3B+. ES works fine.
• My ~/RetroPie/roms folder is a symlink to a roms folder on a mounted external USB drive.
• Built-in ES manual scraper works fine.
• When I run the scraper from the RetroPie-Setup/retropie_setup.sh script, it outputs the same hash number a few times and then promptly finishes with ROMS have been scraped. It has accomplished nothing though, the gamelists are the same from the small amount of ES manual scraping I did.
• I tried running the scraper directly using /opt/retropie/supplementary/scraper/scraper --rom_dir ~/RetroPie/roms, but also no luck. the output was:
