A couple of days ago, my TV library started acting up. Turns out, there seems to be something wrong with the tvdb scraper - as soon as it starts to scrape a newly added TV library, shows quickly show up and then disappear as soon as the next show is scraped.
Similarly, once the whole process is done, the library is completely empty and looking at just the Files view, nothing shows. Adding the same folder without setting it to tvdb scraper, the files are visible like one would expect... This happens both on Eden Beta 2 as well as Beta 1 now (I downgraded to see if that helps)
