Describe the bug

When running the command "/tab reload" in-game, the plugin fails to enable and throws an IllegalStateException related to player head components.

The plugin works correctly on server startup and also when executing "/tab reload" from the console. The issue only occurs when the command is executed by a player in-game.

Expected behavior

The "/tab reload" command should reload the plugin safely without throwing any errors, regardless of whether it is executed from the console or in-game.

Steps to reproduce

1. Start the server with TAB 6.0.0 on Paper 1.21.11.
2. Join the server as a player.
3. Execute the command "/tab reload".
4. The plugin fails and logs an IllegalStateException.

Additional info

• TAB version: 6.0.0
• Server software: Paper 1.21.11
• The configuration was freshly generated (default config, no modifications).
• Layout feature is disabled.
• No custom head components are configured.
• The issue does not occur when running "/tab reload" from the console.
• Error message:
  java.lang.IllegalStateException: Player head component does not have id, name or skin set

This suggests a possible issue with component re-initialization during reload, potentially related to player head rendering or MiniMessage parsing.

Checklist

• I am running latest version of the plugin
• I have read the wiki to make sure it's not an issue with configuration
• I ticked all of the boxes without actually reading them
• I have read the Compatibility wiki page and am not trying to run the plugin on an unsupported server version / platform
• I am willing to cooperate to get this issue resolved faster, including providing any additional information requested or testing new builds

Can you include example configuration that reproduces it?

Hi Neznamy, I've looked into the error more closely and it might not be entirely your fault. I recently implemented the FancyTags plugin ( https://modrinth.com/plugin/fancytags) on my server. This plugin allows you to create tags or prefixes without needing texture packs, taking advantage of the new "Head" component implemented in version 1.21.9. The tab plugin configuration I'm using is the default and doesn't have any errors. I just think you haven't implemented that component in the TAB plugin. Although, I'm not sure if it's as simple as I've described, or if other factors might be involved. The actual error occurred when... 1. I added the %tags_admin% placeholder to the prefix (using luckperms). 2. I typed /tab reload. What happens is that the chat plugin I'm using, or Minecraft chat in general, works fine with the head component, but the tab plugin doesn't. That's why the plugin works when I type `/tab reload`, because it doesn't need to display any `head` components. I hope you've read everything; I may have gone on a bit, but I wanted to be thorough. I hope you can find a solution. I've already given feedback to the FancyTags plugin developers as well. El mar, 7 abr 2026 a las 7:50, NEZNAMY ***@***.***>) escribió:

What does %tags_admin% return exactly? I still haven't seen the stack trace of the error.

[jonathanthxd]

About 2 or 3 player heads depending on the image size, like in this image.

Do you have the raw text string?
