I've been told by every mod involved in this error that it isn't their problem, that they are just listeners. So here we are.

I can't post the FML Latest file as it's too big for pastebin.
Hello, I'm currently working on a modpack with a few friends of mine and we have run into this error posted at http://pastebin.com/GnnXC2TT. The server isn't crashing, so there is no crash log but that is what the console spews out every save. If you need me to post anything else I can.
