Tomodachi Life Switch Update 1.0.4 Save & UI Fixes

Nintendo has rolled out a new software update for Tomodachi Life: Living the Dream on Nintendo Switch, bringing the game to Version 1.0.4. The patch is centered on stability and UI fixes, including rare save corruption after using Island Builder and several issues affecting progression and how Mii characters appear on posters around the island.

Latest announcement: Version 1.0.4 is live

The update, released July 22, 2026, moves Tomodachi Life: Living the Dream to Ver. 1.0.4 and targets multiple bugs reported around island building, character interactions, and poster displays.

What changed (patch notes)

Fixed a rare case where using Island Builder could corrupt save data, preventing the game from launching in later sessions.
Fixed an issue where the game might not progress correctly after resolving a Mii character’s concerns, causing an error and closing the game.
Fixed posters at the clothing shop where Mii characters were not displaying correctly.
Fixed poster selection at the Ferris wheel and news station where Mii characters could be unevenly selected.
Addressed additional issues to improve overall gameplay experience.

Practical impact for players

If you use Island Builder regularly, the biggest fix is the rare save corruption problem that could stop the game from starting later. The update also reduces the chance of getting stuck (or crashing) after completing a Mii’s concerns, and it corrects poster-related presentation issues so character displays at specific locations behave as intended.

Platform scope and what comes next

This update applies to Tomodachi Life: Living the Dream on Nintendo Switch. With Ver. 1.0.4 now available, players should see the stability and poster display improvements after updating through the Switch system’s normal update flow. More changes aren’t listed beyond “other issues” in this release.
