Explanation of issue:
Hi, so I'm using essentialsx on my thermos (pixelmon) server and I'm getting this issue: http://pastebin.com/1zKk4fRK it spams this each time a player pings the server on the server list. Is there a chance this can be fixed or would I have to try reverting to an older version? I used the latest as spigot stated it should work with 1.7

Also, I showed this to the essentials people and they said that it was a thermos issue : EssentialsX/Essentials#880
How to recreate this issue:
use essentials and ping the server on the serverlist

I am not getting this issue at my server - we are also running essentials (not essentialsX) - but a custom fork of the original one without any issues

You said it, custom fork. EssentialsX tho is much better than essentials as it provides some awesome additions. It would be really nice to have this fixed

[KasperFranz]

My custom fork doesn't really have any special things besides changes to how the prefix/suffix works ;).
