Normally I wouldn't put this here, as it seems to be an issue with Netty (whatever that is, it has me stumped) however there's a line in the middle (at com.pahimar.ee3.handler.PlayerEventHandler.onPlayerLoggedInEvent(PlayerEventHandler.java:58) that makes me think it MIGHT belong here.

this started happening after we placed down a calcinator, an aludel base, and a Glass bell. It didn't happen immediately, and we made some nice Aeternalis Fuel first, but then one of us crashed, and tried to log back in, and ever since then anyone who tries to load that chunk crashes the server. Sorry if this really isn't your issue, if not it'd be great if you could point me in the right direction so I can give it to whomever needs it. Sorry for bothering you, and thanks for the work you do.

I had a similar error with entering the GUI of a research station. Any attempts to reload the world result in the a similar crash: http://pastebin.com/g3SS3R7r.
