Adalia Fundamentals appears to be broken right now, at least for me.
The library page section doesn't seem to be working at all. Manual sort has completely failed, legacy box art isn't appearing, so forth. The only thing that changes when I change any of the settings is that, when I increase the number of displayed games... the widget to change pages disappears. No more games are displayed on the first page; it just removes the ability to move to the second. (I have less than 200 games on GOG at this point, so I don't know what would happen if, for example, you had 300 and increased the "games per page" setting to 200. Maybe it would have no effect, maybe it would break in the same way, or maybe it would break in a new and interesting way.)
The forum search addition appears, but the search itself does not work.
The only things that change on the game pages, so far as I can tell, based on my alterations to Adalia Fundamentals settings, is the added links to forum pages and the GOG DB. The "read more" link still appears even when I have it set not to, for example, and review numbers and sorting are both done exclusively by the GOG default funtionality.
Adalia Fundamentals is listed as installed and active. I also have Barefoot Essentials, and that still works fully, so the problem doesn't appear to be with the browser or with Greasemonkey, but in case it's relevant (you never know with troubleshooting), I'm using Pale Moon and the Pale Moon Greasemonkey variant, on Linux Mint 21.3. Any ideas about what is going wrong would be greatly appreciated.
