I had intended to rename it "Classic" back in April, but apparently forgot to update the English localization. (I did change at least Esperanto, haven't checked the others.)
Bah, I still think it would be nicer to give it a 'proper' name - suggestions of "Gold", "Straw", "Ochre" all sound more interesting to me. And having "Nostalgia" and "Classic" does seem a bit silly...
Change is now made for en; other languages with custom skin names should update as necessary.
