Corrupt Sonic analysis?

The tidying up was for mixtapes , artists , live albums etc that dont appear on musicbrainz the main concern was losing ratings .

The plex dance was in refrence to removing either the entire library or sections to try and identify what files were causing the strange sonic issue .

Media Server debug logging is enabled not verbose .

When the server shows the 11 albums being scanned there is nothing i can see that shows what if any albums are being sonic analysed.

But when i transfer 1 album over i can see it being analysed in logs the number of albums analysiing is now 12 , the new album get analysed and then just sits at 11.

Is it possible a non standard charachter in some file names would maybe cause an issue ?
