When you move a co-op world to your server, the character you played as the host is saved under a special co-op ID, so the game does not know it belongs to your account yet. Attaching links that character to you, and we take a snapshot of your world first. If you attach the wrong character or change your mind, you can undo the attach from your server card or from the Backups card in Server Settings. Undo restores that snapshot, so your world also rewinds to the moment of the attach.
In co-op, Palworld saves the host's character under a fixed internal ID instead of your Steam account. Your friends' characters are saved under their real accounts, so they carry over automatically. Yours needs one extra step: telling the server "that host character is mine". That step is the attach.
Nothing is lost while you decide. The character stays in your world files, and every attach starts with a snapshot of the world exactly as it was.
The easiest path needs no IDs at all:
Start your server and join it once on Steam, Game Pass, or console.
Open your dashboard. The server card shows a notice that your host character is not attached yet. Open it and pick yourself from the list of players we saw join.
Confirm. The attach runs the next time the server starts, and your character is waiting for you when you join.
If you know your SteamID64 or Steam profile URL, you can enter it instead of joining first. Look for I know my Steam ID, let me enter it in the attach window.
Missed the notice or chose I'll start fresh and changed your mind? The attach also lives in the Backups card in Server Settings: select the backup made when your world was imported and use Attach my character.
Undo is a restore of the snapshot we took right before the attach.
Right after an attach, the server card shows Character attached with a Wrong character? option. That is the quickest undo.
Any time later, go to Server Settings and expand the Backups card to its full view. If a character is attached, you will see an Attached character section at the top with an Undo attach button.
In the backups list itself, the snapshot from just before the attach carries a Pre-attach snapshot badge. Restoring that backup does the same thing.
Important: undo rewinds your whole world to the moment of the attach. Anything that happened on the server after the attach (building, catches, progress by other players) is rewound with it. The undo works for as long as that snapshot is still in your backups list.
Deleting your character's file by hand does not give you a fresh start. The world still remembers the character, and the game will refuse to let that account join. Use I'll start fresh in the attach notice instead, or attach and then undo.
Re-uploading your world does not detach anyone. It replaces the whole world, including everyone else's progress.
There is currently no way to detach your account while keeping the world as it is. Undo always means rewinding to the pre-attach snapshot. If you need something more surgical, message us and we will look at your case together.
Ping us on Discord or send a ticket from your dashboard. Include your server name and roughly when you attached, and we will find the right snapshot with you.
Moving your co-op world to your server: the attach is step two of that guide.
The map looks dark for everyone after a move: exploration is saved per player on their own PC, see the black map article.
Console and Game Pass players cannot be looked up by Steam ID; the join-once path above is made for them.
