Developer Mojang has warned anyone playing Minecraft through the Xbox app on PC not to download its latest update as it could cause their worlds to disappear.
That warning comes via Mojang’s official Minecraft service status social media account, which writes, “Do not update Minecraft through the Xbox app on PC. If you do, your worlds may be lost.” Mojang instead recommends players first run the Gaming Services Repair Tool for PC, accessible through the PC app, before installing the new update.
Minecraft’s Game Release Known Issues page takes the explanations a little further, saying that using the repair tool will update Microsoft’s Gaming Services to version 19.87.13001.0, which will avoid the update error, and presumably prevent all resulting world-snuffing mayhem.
