When I try to boot up Hyrule Warriors, a screen pops up saying "installing update to system memory". I haven't let it complete the update, and it gives me an option to cancel. If I tap "cancel", I receive the message "return to Wii U Menu. The game cannot be started until the software is restarted and the updated data has installed". I'm almost certain it isn't a system update, but it looks very much like one. Should I go ahead on this update? I've tested Smash 4, no update screen pops up with that game. I'm not connected to the internet either.
