Movies not being recognized

Ok, I’m curious what’s going on. I’ve been converting my DVD’s to MKV and have them in the structure of:

movies

  • Star Trek
    • Star Trek.mkv
  • Clue
    • Clue.mkv

But lately I’ve been adding movies, and they’re not being picked up by Plex. And its been deleting movies off my drive! I added Fantastic Beasts, and the .mkv

I told Plex to rescan the movies folder, and it didn’t even find the folder to try and download the metadata. I came back later and looked on the drive the movies are stored on, and that whole directory is missing.

What am I doing wrong? How are movies being removed from the drive???

Nevermind, resolved itself
