Playlists Deleting Tracks

Server Version#: 1.43.3.10896
Player Version#: 4.12.4 iOS

I don’t know what happened but Plex stopped detecting my media and I didn’t notice so I tried downloading a playlist and then it deleted every track it couldn’t detect instead of i dont know leaving the playlist as it was. This is extremely frustrating because I have to rebuild every single one from scratch.
