The issue template exist for a reason, please follow it. With that said I doubt essentials is the one causing your issue.

Don't put anything inside this block, as it won't be included in the issue.

You can ignore the template if suggesting a feature; otherwise, read on:

1. Fill out the template, running the commands either in the console or
   as a player. Don't simply put "latest" or we will ignore it.

   of the template. Avoid using Hastebin or Pastebin, as files are deleted
   after a period of time.
3. If you are reporting an issue with lag, please include a timings report.
4. If you are reporting an issue with messages or in-game behaviour, please
   include screenshots detailing the problem.

This doesn't look like an EssentialsX issue.
