Well if it's the costume DLC that causes the codes to not work it'd probably be more helpful to put 'can't be used with costume DLC installed' as a note in the psv
This is also why I suggested that people who create codes should note what DLC they had installed when they made the codes, or ensure they have all DLC/whatever is available before making codes and note that it needs all DLC to work.
