I'm using version 37.2 in hardcore classic.

Did you delete a character recently (from the Baganator UI or via the Syndicator slash commands)?

I deleted a character.
I did not use the slash commands. I removed from the savedvaraiable file(s). I didn't know there was a slash command.

You'll need to find the other instance of the character's name in the saved variables and remove that too.

I didn't transfer the character/guild delete or hide commands documentation to the Syndicator page when splitting the addons up a while back, so have added it now.
