What bug is Yoshi’s Switch 2 game?

Nintendo investigates a game-breaking Yoshi bug, then patches it

Nintendo is investigating reports of a game-breaking bug in Yoshi’s New Switch 2 outing, titled Yoshi and the Mysterious Book, and has since followed up with a fix.

After launch, some players reported that the issue could significantly disrupt progress or functionality enough to be considered “game-breaking.” Nintendo’s response was to open an investigation and later confirm that a patch has gone live, addressing the immediate problem.

This matters for Switch 2 owners because early-iteration issues can be especially disruptive during the console’s adoption phase. A patch being available quickly also reduces the risk that affected players will need to stop playing or wait months for remediation.

It also highlights how Nintendo’s early Switch 2 software rollout is being managed: keeping games playable enough to retain trust, then resolving deeper stability problems once they can be reproduced and assessed.

For players, the practical takeaway is to ensure the title is updated, since Nintendo has now moved from investigation mode to delivery of a patch.
