I'm experiencing the issue whereI get kicked out of the game after about a minute at the Galacticraft destination selection screen when I have both mods installed (with or without other mods). Here's the error: http://pastie.org/9484899

I already opened an issue on Galacticraft's tracker and we determined it's likely not on Galacticraft's side. more details here: micdoodle8/Galacticraft#878

This isn't Galacticraft. I can somewhat easily reproduce this. Just standing around an agrarian skies like mob spawner (22 blocks drop, water to the sides and 4 spawning pads) will crash within a few minutes. It's probably sending a hat that's more than 32KiB in size or something related to that.

Used a modified Forge version that appended the channel name to the message and Hats was the appended string.
