Microsoft warns about Minecraft update leading to lost worlds for some players
The latest Minecraft update for Bedrock was released on March 12, and this 1.20.70/71 update is causing a game-breaking error that could cost you every world you’ve ever made. Because of this, Microsoft issued an official warning on March 15.
This issue is specifically for players who use the Xbox app on PC to play Minecraft, so if you’re on another platform, you don’t need to worry too much about this issue. It’s probably a good idea to save backups of your worlds or avoid playing for now just in case, though, as it’s always possible this issue could end up affecting other platforms too.
