Oh, I should confirm that the original NFO files used have been generated by simply exporting the internal DB. I do not (and have never) used an external media manager to modify them.

I also have backups of my original v90 DB including the actor duplicates so can assist with testing #6020 if you wish. Unfortunately I don't have a build environment though...

@virtuallysafe: Do you have a log of the same import into a v90 db using a non-v91 build, ie #1222? Easiest way to test a fresh v90 db while keeping your existing v90 db would be to set a <name> property for the video db in advancedsettings.xml.

For info, I've *never* exported/imported any NFOs. I have however deleted episodes when the NFO plot has been empty, refreshing the show once the episode NFO has been updated with a suitable plot. I'm wondering if this is a potential cause. All my tvshow NFOs are generated by Sickbeard.
