Ok I recently upgraded to luma 9.1 from Sky. I can't restore my AC:NL save because it was from the updated version AC:NL Welcome Amiibo. I have all the known nintendo URLs blocked on my router. I updated AC:NL on my other Luma system a week or two ago and nothing bad happened. Is it safe to unblock nintendo long enough to perform this update? Otherwise I guess I would need an updated CIA or something, right?
