When the Norwegian team finds the note Lily left for Dwight, the word "cemetery" is spelled correctly (close up of note). When the team shows that note to Vivian, it is spelled incorrectly "cemetary", and then spelled correctly again when Vivian shows the note to Lily.
Aside from the misspelling on the note, it was obviously not the same note because the "L." in the signature isn't the same shape.
