Follow this template except for feature requests. Use pastebin when providing /protocol dump and any relevant errors.

Make sure you've done the following:

  • You're using the latest build for your server version
  • This isn't an issue caused by another plugin
  • You've checked for duplicate issues
  • You didn't use /reload
