The following message occurs if you enable nothing but SilverDragon, Cartographer Notes, and their dependencies, but disable the option for showing those notes within the SilverDragon settings.

I had recently disabled the option of showing those notes because they're basically just all over the place. I understand the desire to have the rares shown wherever they are seen, but it makes any reasonable location gathering fairly difficult with the way the notes tend not to be just where the rares path, often because of either coordinate bugs, or because the mobs were pulled away.
Unfortunately, above error pops up all the time if I turn off this option, while the addons themselves don't show any further issues.
Hopefully someone can fix at least the error, so that the setting doesn't generate the error message anymore.
