Nintendo has decided to release a brand new update for Mario Strikers Battle League. This is the first update to release since the big 1.1.0 update that launched last month. Once you update the game, Mario Strikers Battle League should be at version 1.1.1.
As for the official patch notes, they don’t say much. In fact, the only thing that Nintendo mentions is that they “fixed an issue where the goal keeper would sometimes fail to react to a free lob pass from certain positions, which would result in a goal being scored”.
