Yes I am aware that there was an explanation posted on how to fix it after updating over the Universal Updater. I've read through this post #animal-crossing message
My confusion stems from what I am dragging over. Am I replacing the Nimbus folder in my 3ds? Do I need the "nimbus.3dsx" file too?
I'm aware these are all questions that should be obvious to most people. I struggle with exact instructions and I don't want to mess something up bad. I apologize if this annoys people.
