Mario Kart World 1.2.1 Patch Released

The latest Mario Kart World update fixes a ghost race bug and tightens online play requirements.

Mario Kart World 1.2.1 Patch Tightens Ghost Bug and Online Play

Nintendo released Mario Kart World version 1.2.1 for Nintendo Switch 2 players. The update fixes a bug where downloading a ghost in Time Trials could cause the game to race a different ghost when selecting Race with Ghosts or View Replay. Online play now requires the latest patch, and players on version 1.1.2 or earlier cannot race online with others on the newer version.

The patch follows a patch issued a couple of weeks earlier, signaling ongoing maintenance for the game. Nintendo notes this is a targeted fix rather than sweeping changes, prioritizing stability and the integrity of online rankings.

The update cadence signals that Nintendo treats online stability as a core service rather than a one off tweak. By focusing on a specific bug, the company avoids risking broader changes that could disrupt players.

For players, the update creates a shared code baseline that makes online play predictable. The requirement to update quickly can be a barrier for casual fans with limited bandwidth or slow connections.

Highlights

Online play keeps racing fair, even when the fixes are small
