Mii Fighters are breaking Super Smash Bros. Ultimate matches on the Switch 2

It's a big day for everyone who has successfully acquired their Nintendo Switch 2, but few hardware launches go off without a single hitch. In addition to some surprising hidden costs to finishing the Nintendo Switch 2 Welcome Tour, players have also discovered a compatibility problem in Super Smash Bros. Ultimate.

The conditions for this issue to occur, luckily, appear to be pretty narrow. It's happening in online matches of the fighting game where one person is on a Switch 1 and the other is on a Switch 2. If one of the players choses the Mii Fighters as their character, the match may immediately end. Also, thumbnails aren't always saving correctly for the Mii Fighters, which are customizable for each person.

Nintendo is aware of the problem, according to a translation posted on X by user OatmealDome. The game company said that an update for this Smash compatibility issue will be released "soon," although no more specific date has been provided. Basically, if you're going to spend launch day with your Switch 2 playing Super Smash Bros. Ultimate, just don't pick Mii Fighters.
