DVR makes file on disk, but does not show up in Library

Server Version#: 1.43.0.10492
Player Version#: Web 4.158.0
Tuner Make/Model: Hauppauge WinTV-HVR-22XX

I have Plex set up to tape a few shows - this used to work great. However, at some point, Plex stopped detecting newly-recorded shows: the DVR still makes the recordings, but they do not show up in the destination library.

Doesn’t seem to be a permissions issue; Plex has rwx permission to the target recording folder, and both working and broken recordings are created as 644 plex:plex, per normal.

If I make a copy of any of the broken files, suddenly the copy shows up fine.
However, if I simply rename the broken file, it does not show up. Curiously, renaming the file causes a flurry of warnings - see last few lines of main Plex Media Server logfile in zip below.

Any ideas?

I updated to latest Plex beta and the issue…magically resolved itself?

Spooky.
