Troubleshooting

The most likely causes, in order:

1. You are holding a normal pickaxe, not the plugin's one. The plugin recognises its own item by the way it was handed out. An ordinary netherite pickaxe from your inventory will not work — you have to get one through /grzybcio-kilof.
2. wymagaj-uprawnienia: true is set and you do not have grzybciokilof.use. Then the pickaxe deliberately behaves like a normal one. Check with /lp user <nick> permission check grzybciokilof.use.
3. The block is on the exclusion list. Bedrock is there by default. Check bloki-wykluczone in config.yml.
4. The pickaxe was handed out before a config change. If you changed kilof-typ, older copies may no longer match. Give yourself a fresh one.

Look for lines mentioning GrzybcioKilof in the console. Typical messages:

Also check /plugins in game — GrzybcioKilof should be green. Red means the plugin is loaded but disabled.

/grzybcio-kilof reload needs the grzybciokilof.reload permission, which is separate from grzybciokilof.give. This trips people up often — someone can hand out pickaxes but not reload the plugin.

If you have the permission and the reload still fails, it is almost certainly a YAML syntax error. The usual suspects:

• Tabs instead of spaces. YAML does not accept them.
• No space after a colon. It has to be kopanie-promien: 1, not kopanie-promien:1.
• An unclosed quote in one of the messages or in the pickaxe name.

Paste the file into any YAML validator — it will point at the line.

Instead of a colour you literally see &#7ED4E6. Possible causes:

• The server does not support HEX. HEX colours work from Minecraft 1.16 onwards. On older versions use the legacy codes (&b, &a, &e).
• Wrong format. It has to be &#RRGGBB or <#RRGGBB> — six characters, no spaces, no dashes.
• A typo in the colour code. &#7ED4E (five characters) will not be recognised.

Check whether another plugin on your server hooks the block break event — typically land protection, anti-grief or a custom mining economy plugin. When two plugins handle the same event, the second one can cancel the drops.

Quickest test: disable the suspects one at a time, restarting after each.

Check kopanie-promien in config.yml. At 3 a single swing is 49 blocks — with a few players at once that is hundreds of operations per second, plus drops and lighting updates.

Drop back to 1 (3×3). If the lag persists, check /timings or /spark — the problem is almost certainly somewhere else.

By default the plugin touches everything except bedrock. If players are losing chests, spawners or blocks from other plugins, add them to bloki-wykluczone:

bloki-wykluczone:
  - BEDROCK
  - SPAWNER
  - CHEST
  - TRAPPED_CHEST
  - BARREL
  - SHULKER_BOX
  - ENDER_CHEST
  - BEACON

Then run /grzybcio-kilof reload.
