Nintendo Switch 2 has a ton of free updates available for existing Switch games, with a bunch of first-party Nintendo games getting the rub (especially Pokemon Scarlet and Violet, which desperately needed it). While Super Smash Bros. Ultimate is among the games that run better, it comes with an unexpected downgrade.
Twitter user OatmealDome noticed on the US Eshop page for Super Smash Bros. Ultimate that the game is listed as "Supported – Game progression may be affected in portions of the game" for Switch 2. When you look for more info, it turns out there's not a progression issue; it's actually just that Mii Fighters are not working as they should.
