Test mcMMO party invitations before changing membership limits

Applies to: mcMMO; match the linked maintainer documentation to your installed platform and release.
Documentation checked 9 November 2026.

A rejected party invitation can come from party state, permissions or a configured limit. Reproduce the rejection before removing members or recreating a production party.

Check the installed content

mcMMO progress belongs to player data, while its configuration controls future skill behaviour. Preserve both before changing progression rules. Match the installed release when checking permissions and configuration; current configuration references identify changes that require a full server restart.

Work through the change

1. Record the invitation message, party membership and the inviter role. Consult the installed party and permission references for leadership and membership requirements.
2. Create a disposable staging party with ordinary accounts. Confirm the leader can invite one eligible player and that an unauthorised member cannot perform restricted management actions.
3. Compare the failing production condition with the test, including membership limits, another party membership and any documented invitation restrictions. Change only the relevant staging setting.
4. Test acceptance, a deliberately ineligible invitation and departure from the disposable party. Check that membership counts and shared features update after a normal restart if configuration changed.

Verify the result

Eligible invitations should work within the intended limit, while rejected cases should have an explainable rule. Existing production membership and player skill levels should remain untouched.

If the result differs

If the test works but the reported invitation fails, compare account permissions and current party state. If every invite fails, inspect configuration load errors and leadership permissions before increasing limits.

Keep a recovery path

Restore the original membership setting and remove the disposable test party through supported commands when finished. Keep production party storage backed up and avoid deleting a real party as a diagnostic shortcut.
