i lost all my stuff when i logged into my server

Is cracked enabled?

Since your server has cracked enabled the uuid is bound to the username

Here are some ways to get them back

Option: Go into creative mode or simply cheat them back

Option 2:

• Make a backup of your server (this is highly recommended)

• Download your world

• Find your new uuid here

• Navigate into the playerdata folder and find your old uuid

• Rename your old uuid into the new uuid

• Upload the world
