When a player joins the server, there is an exception that occurs (build 363)

I'm using Spigot 1.10.2

Plugins: Essentials, EssentialsSpawn

It says you are running build 354 in the error. Try a reboot.

Well I feel silly now. Figured out what I did: Used the main plugin from the spigot page and essentials spawn from jenkins. Thanks.
