TVDB scraper doesnt find new files

I’m using the built in scraper for tv shows, which has served me well for years. But after updating Kodi from 16 to 17.1 I started getting problems: When I update library, the scraper no longer finds new files in my tv shows folder. Movies are added like before so far that I can tell, but 9 out of 10 times it ignores new episodes.

I changed nothing in my hierarchy, and there doesn’t seem to be a correlation between file formats and whether its added to the library. I’ve googled a lot to no avail; I can’t find a thread describing the same issue I have. There are no error messages, nothing like “failed to blahblah”. Scanning the library appears to work as it should; it looks through the folders and concludes with there being no new episodes to scrape.

So here are the details I can think, please ask what else I may provide to figure it out. I know one often add certain logs to these posts, but I have never done that before so I’ll have to look up some instructables if thats necessary. Though, with no errors and everything appearing fine, I would guess that the logs would only show what appears to happen: “scanning…no new files…finished”

HIERARCHY:
TV SERIES FOLDER
-[SERIES NAME]
–SEASON 1
—[SERIES NAME] S01E01
—-[ACTUAL FILE] (MKV/HEVC/ACHIVES)

I always kept tv shows stored like this, and it never caused any problems at all. Some times the episodes will be placed directly in season folder. Other shows may have separate folders for each episodes due to multiple achive files or organizing of subtitles. Extracting archives does not help, files are still not found. Moving episodes out of their separate folders and storing them directly in season 1 folder, makes no difference. All formats listed over are ignored equally by the scraper, though on a rare occasion files are found and added like they should. Now I have to add episodes manually, and even that doesn’t always work.

SCRAPER
The TVDB built in 1.8.4: Always used this one, found no reason to replace it, neither are there good alternatives that I know of.
The TVDB 1.8.4.1: Shows up as an alternative, no idea why the built-in one wont update itself sinse theres apparently a newer version. Downloading this causes two separate addons with its own versions; neither can be disabled or removed. But choosing one or the other in “change content” windows, makes no difference.
XEM: Tried it for the hell of it, though if I understand correctly, it scrapes via TVDB like the others anyway and shouldn’t make a difference besides numerating of episodes. Results are the same.

TRIED WITHOUT RESULTS:
1: Clearing out my library, scanning it all over, with all 3 scrapers listed over. A majority of old shows are added, eventhough info has been deleted. New files are however still not added.
2: Extracting archives
3: Moving files out of their separate episode-folders
4: Changing season folders names to “season 1” or “showname season 1”
5: Different file formats are treated the same, I tried other common formats

THE ONLY FIX SO FAR:
1: Via video\files\showname: I tried “scan for new content” on specific shows that had new files added. This doesn’t work.
2: Via video\files\showname\seasonfolder: Scanned season folder for new content, doesn’t help, no matter if the episodes are archives, mkv, hevc, or if they are placed directly in the season folder or in separate folder.
3: Via video\files\showname\seasonfolder\episodefolder: Scanning episode files or folders directly, will work SOME times, if not the option “add to library” works here.
