Odd crash when loading a world in modded 1.6.2

[UltraX7]

So I'm currently building a modded setup of 1.6.2 with Forge... I've had some problems here and there, and resolved them thanks to the crash reports and error logs, but now I've come across a problem I can't fathom the cause of:

 

Crash report - http://pastebin.com/cK3qpcWC

Forge log - http://pastebin.com/HWuWMN1w

 

The game boots fine, but when I try to load a world it crashes to the launcher and presents me with the crash log.

Can anyone help me out? Thanks

We do not support.1.6.2 anymore. And one of your mods fucked up.
