Our investigation so far suggests that if you load the game and do not do anything that would trigger a save (i.e. - enter fully in story mode, finish a multiplayer brawl, buy an item, complete a brawl, enter a new area, etc.), your saved data has a high chance of being corrupted.

To prevent this we suggest making sure that before exiting the game you do either one of these:

  1. Completely load into Story Mode, until you see your avatar in the game
  2. Play a full multiplayer game brawl and fully come back to the Brawl Online lobby
