Console errors running the latest spigot 1.14.3 and EssentialsX-2.16.1.215. https://pastebin.com/KqQGAfup

Getting this when joining the game: https://pastebin.com/83r3RjF5

And this when trying to type /killall drops (though spams errors for any command it looks like) https://pastebin.com/aAqQxKY9

also this on startup: https://pastebin.com/G0U9UPam
although I didn't expect this to work immediately by any means since it's not officially supported yet.

This has now been fixed - you can download the latest version from the downloads page.
