Nintendo has released another update for Mario Kart 8 Deluxe, following the surprisingly robust 4.0.0 update last month. The latest update, Version 4.0.1, doesn’t add any fresh new content, but it does fix a few important bugs when playing on Nintendo Switch 2. Most notably, the number of item boxes and obstacles should now be fully consistent online with other racers on the original Switch, as apparently Switch 2 players previously had an unintentionally increased amount of them appear on the track. The full patch notes for Version 4.0.1 can be found below.
