Troubleshoot Advancements Not Syncing Between Teammates

Check Team Membership

The most common reason advancements don't sync is that players aren't actually on the same team. Verify membership using:

`

/team list [team_name]

`

This shows all players currently in that team. If a player is missing, add them with /team join [team_name] or have an operator add them using /team join [team_name] [player_name].

Verify Mod Installation

Confirm the mod is installed on the server. The mod is server-side only, meaning it must run on the server to function—clients don't strictly need it installed, though installing it client-side can help with LAN worlds.

Restart if Needed

If players were added to a team after joining the server, try logging out and back in. Sometimes the mod needs a fresh connection to recognize team changes and begin syncing advancements properly.
