Not happy.

The game-breaking troubles continue for Nintendo with Wii Fit U. Only weeks after the glitch in Pokémon X and Y was put to rest, it has now come to the attention of Nintendo that players may encounter an error causing Wii Fit U or the trial version of the game to lock up when attempting to transfer save data from Wii Fit or Wii Fit Plus.

According to Nintendo Australia, the error occurs if all of the following conditions are met:

Two or more sets of user data were created in Wii Fit or Wii Fit Plus and the data created earlier was deleted.

A Mii character used in Wii Fit or Wii Fit Plus is registered in the Wii U Mii Maker.

The data from Wii Fit or Wii Fit Plus is transferred to the Wii U.

To resolve the problem, Mii characters in the Wii U Mii Maker that have been used in Wii Fit or Wii Fit Plus, along with any transfer user data, must be deleted and then re-registered in each piece of software.

With any luck, Nintendo will patch this soon. In the meantime, tell us if this problem has affected your Wii Fit U experience, or if you’ve even suffered from the recent Lumiose City glitch in Pokémon X and Y.
