Explain why a player-placed block gives no mcMMO XP

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

Blocks placed by players may be treated differently from naturally generated blocks. Check the anti-exploit rules before increasing rewards or disabling protection across the server.

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 skill, block type and how the affected block was created. Keep a naturally generated comparison area separate from the player-placed test area.
2. Read the experience reference and installed configuration for source eligibility and exploit prevention. Do not assume a visually identical block has the same reward history.
3. Mine one permitted natural block and one deliberately player-placed block with equivalent tools and account permissions. Record XP, drop behaviour and relevant plugin messages.
4. Repeat with an unrelated supported block source and check any world or region restrictions. Change only the specific staging rule if your gameplay design deliberately allows that source.

Verify the result

The observed XP should match the documented source policy, with the natural control confirming that the skill itself works. A blocked repeat-placement loop should remain blocked unless you intentionally redesign the economy.

If the result differs

If neither source awards XP, inspect the skill permission and world rules first. If rewards occur inconsistently, check other plugins replacing blocks or handling breaks before weakening anti-exploit settings.

Keep a recovery path

Restore the original source policy if the trial permits a repeatable XP farm. Remove only expendable test blocks and keep player levels intact; a source-eligibility issue does not require deleting skill data.
