no joy, still same errors on @ Version 1.13.8.5395
It happens when I scan my music library (plex premium), I moved a bunch of files out of the plex main music folder (so I can do the plex dance, to get rid of tracks with dates in the future).
for reference see @ Plex music - recently played music - sorted alphabetically by artist?!?
While in the linked thread, I manually cleared the bad data, I noticed these database errors (not sure if they were happening before or not).
So I restored to backup database (from before I modified the db), a few times now with different backups.
And yes, I stopped plex while modifying/copying/restoring.
My plex seems to function completely normally, aside from these errors spamming the log file during a music scan.
I have not yet let if finish scanning (since I started noticing the db errors), so I am going to let it sit all night/day until it does, then do empty trash/bundles/optimize and see what happens.
