Heyop,
Firstly, there are no errors when this occurs.
Using the latest version of EssentialsX, Nametagedit and Paper Spigot, every so often I get this: http://i.imgur.com/sVzWG5p.png
https://hastebin.com/derowibeca.coffeescript is my essentials config.
https://hastebin.com/aguqewucov.bash is my NameTagEdit config.
Let me know what's happening, thanks :)

Actually did some more research, it's in Essentials, is there a way to make NTE take priority?
See issue on Essentials here: EssentialsX/Essentials#1033

Doing /nte reload fixes it until someone else goes AFK again.

Apologies I was on vacation. Will try to test this issue soon, unless you have found a workaround or EssentialsX has updated?

Perhaps a dirty solution would be to have nametagedit function on more of a delay (and listen for an event within essentials), so as to ensure we overwrite any other plugins. The downside though is that the tag updates won't be immediate and it'll look slow, and it might flicker when someone goes AFK.

No workaround sadly, it still happens on later versions.

Any update @sgtcaze as to why it's not working properly? Thanks

Going to test around with @JustOneMoreBlock and see if we can come up with something efficient and not too invasive. Thank you for your patience!

Hey again. To clarify a few things, in your config.yml for EssentialsX, what is the setting afk-list-name set to? EssentialsX allows you to disable the Tab List name change for AFK players. With this setting disabled, when I go AFK on my test server my name in tab doesn't change.

If you've tried this, may you repost your configs? (as you know hastebin removes them over time)

{PLAYER} is what it is. I set it back to none and it appears normal. Is there a way to let console know about this rather than making it look messy in tab?
Ta!
