I just migrated my laptop to a new disk. My home folder (I'm on Linux) was copied from the old to the new -- so the calibre folder is the same. Right after I did this, there was an update to Calibre (to version 6.12).
After this, I noticed the plugin was no longer storing the readability states. Books that had the stats already still display it. I can manually add numbers to the columns and they will appear in the book details pane.
Log below. Apparently the "copy_reg" module is missing, or has been removed, or something.
