Thumbnails are messed up / Mismatched
The thumbnails for the 'Videos' section on PC are wrong for the last 50% of the files. After the first 50%, the VLC takes a random thumbnail from a file in the previous half of the library. This happens regardless of whether there is embedded cover art in .mp4 and seems to affect all file types. This bug does not occur in the 'Shows' section, which correctly generates the thumbnails for those files.
