Recently the guild officers went through the entire guild roster in game and cleaned up the public notes for each player. They went and deleted a lot of notes that were no longer needed. (probably about 100 note deletions). However when I upload the roster with the new info, All the guild ranks changed correctly, the notes of people that still have a note, have the correct new note, BUT, if their note was removed, the roster is keeping the old note. It is not resetting the note to blank. I have looked through the lua file and the note field is blank. Has anyone else seen this before?

Yes, if you used the search, you would have found this out
