I'll preface this with the fact that I know this error has been reported before. I found the other issues detailing this, but the reply there said it was fixed in the latest 1.14 build. However I'm on 1.12.2 and am using the latest version of EssentialsX, 2.17.0. I really need a fix for this because it's making the server console unusable. I mainly manage my server through that.

Expected behavior
No errors

Screenshots

This is a duplicate of #2635, which concerns 1.13 and below. It is not the same issue as #2529, which is solely related to 1.14+.

EssentialsX version: 2.17.0.0

You aren't running the latest build of EssentialsX - download it from the build server.
