A bug in Pokémon Scarlet and Violet is causing players to lose their save files, thanks to the latest patch.
It’s unclear exactly what the cause is, but many fans on reddit (thanks Kotaku) are reporting the error after connecting to the Pokémon Go app or downloading DLC.
The Reddit thread is full of players losing hundreds of hours of gameplay and shiny Pokémon, some from simply buying DLC.
Although the bug seems to have only affected a small portion of players, the lack of solid knowledge about the cause scares many players.
Last week, The Pokémon Company announced DLC for Pokémon Scarlet and Violet called The Hidden Treasure of Area Zero. It’s available to buy now ahead of its two-part release later this year.
Also announced was the ability to connect Pokémon GO with Scarlet and Violet to collect Vivillon patterns and send postcards.
It seems that connecting to Pokémon GO or purchasing DLC are the two commonly reported causes of the file corruption error.
Eurogamer has contacted Nintendo for comment.
