Hello, I have a very annoying bug with the latest Spigot #771 build. It'll crash the server every few minutes after I start it up. Here's the log: http://pastebin.com/VB41xWuC (Note: It's from down to up, I use Multicraft panel) Somehow, Spigot have trouble with PermissionsEx and Essentials, then it cause crash. Can someone help me? Thanks.
