Hmmm this is how I did things.Did you download and install any update .NSP files for Xenoblade for your console?
-Got Xenoblade 2, installed official update online.
-Days later I got new SD, moved my xci there, told me to update, can't play.
-Got NPS Update but I still can't play since it's not the newest one.
I think I found latest update but it made me wonder why I can play the updated game in one SD and the newer one I can't if my update was supposedly installed in my system
