UUID Data Loader

Shared Player Data allows multiple players to safely share and pass around the same Minecraft singleplayer world without accidentally loading another player’s data.

Minecraft normally stores the singleplayer owner’s player data in level.dat. When a world is given to another player, this can cause the new owner to receive the previous owner’s inventory, position and other player data.

Shared Player Data checks the world’s playerdata folder for the current player’s UUID and loads their own player data when available.

This mod is currently in beta. Back up your worlds before using it!
