Club Nintendo members had some exciting emails this week, as they included Mewtwo codes for the latest Super Smash Bros. titles on Wii U and 3DS. Unfortunately some players experienced a downside, triggering a glitch in the Wii U version that blocked access to online play. In multiple cases players seemed to corrupt their save data by beating the 10-Man Smash mode with Mewtwo, which the game apparently picked up as an attempt to cheat and blocked access to online play.
Nintendo has now issued a notification in Japan to confirm that it is working on a fix for the issue - hat tip to Nintendo Everything for an additional translation. This acknowledges that the issue can also occur on the Nintendo 3DS version, advising players that in some cases the bug can be triggered by a host of modes when played with Mewtwo or those that have accessed the DLC. The case appears to be that the game is falsely detecting the Mewtwo data as an attempted hack, as was deduced yesterday.
Multiple modes are effected, unfortunately, with the following being what we know from the initial details yesterday and Nintendo's update today.
- Trophy Rush
- Trophy Rush
- Smash Run
Nintendo may just be covering its back in advising players to avoid practically every mode that contributes to GSP rankings, but that seems like the sensible option.
It seems wise to try and avoid these modes (with all characters) in both versions until a patch is issued, which hopefully isn't far away. Standard offline Smash mode is unaffected, as is Smash Tour on Wii U, so it seems standard matches and online brawls are the sensible options to avoid any risk of being locked out of online play.
Have you been affected by this issue? Let us know in the comments below.
With thanks to Kazuo Yokoyama for the heads up.
