    You might find that your progress has been lost, on a world you have played before.
    You may have lost your progress due to changing your name in a Cracked server, or
    after uploading a singleplayer world unto the server.

    Here are the steps on restoring your previous playerdata (given that you have full access to the server):

    First, take note of your current of your current UUID. A UUID looks like this:
    123e4567-e89b-12d3-a456-426614174000
    To get your UUID, join the server, then check your console. Your UUID appears alongside your join message. Copy it, and paste it on a text editor.




    Second, turn off your server and navigate to your world folder in Aternos Files. Go to the playerdata folder.
    From here, look for a .dat file that has your previous (or your current) name alongside it, but with a UUID different than the one you just copied. If you find it, download it by clicking on the blue download button alongside it.
    (Tip: if there are many files, you can search for them using CTRL+F)


    Rename the file you just downloaded with the UUID you copied. Make sure to keep the .dat file extension.
    After that, click on the upload button inside the playerdata folder. The upload button looks like this:

    A replace confirmation dialog will appear if you followed the previous instructions correctly. Click on Yes.


    We should be done here. The next time you join, you will have your previous location, state, levels, items and your enderchest inventory.








    However, not everything can be restored: Your pets will forget you, your Villagers will forget you, you will lose your previous OP status (if any), you will lose your whitelist status (if any), and every other thing that uses UUIDs to remember you, will forget you.

    Buy the game and avoid hosting Cracked servers. If your world was not previously a Singleplayer world, you will never have to restore your playerdata like this.

    Every Minecraft account has its own UUID, and does not change even after you change your name in minecraft.net

    In contrast, cracked servers assign random UUIDs to players on the first time they join with a unique username. Piracy players will lose their previous progress when changing their name.

    Paper 1.19 had changed where per world configurations are stored, and they are inside the world folders, including the nether and the_end folders.

    Right now, I cannot access the world_nether and world_the_end folders in my server.

    I have tried disabling world optimization, and I have also tried accessing them while the server is active, but to no avail.

    Access to these folders are required for me to implement Paper's recommended anti-xray settings, in 1.19.

    Villagers remember you by your UUID.
    A UUID is a unique number given to each player. By default, you use the UUID that is provided for your account. By enabling cracked, you now use a random UUID for use in that one server.

    You can't change your UUID. A better solution would be forcing a raid into your village, or infecting then curing those villagers again. Else you might want to disable Cracked.

    You can try reducing the amount of spawn chunks loaded,
    or disabling spawn loading entirely.

    Make a backup first.
    Change your server software to PaperMC,
    try to start the server once (even if it crashes), then stop the server.
    A new file has appeared. Go to Files > paper.yml

    Now, find and set keep-spawn-loaded to false if you want to disable spawn loading,
    or
    find and set keep-spawn-loaded-range to a lower value, like 3.

    Don't forget to save after editing paper.yml
