Error Loading Worlds

[RazzyJam]

So, Im working on a custom modpack and playing in SSP. I can boot up the modpack to the main menu and create a new world without issue. However, when I save and quit the game, reloading any world appears to freeze the game, and after a long time it crashes with the following error:

It looks to me like there is a problem with either NEI or CodeChickenCore, but Im not really certain. Any help resolving this error would be fantastic!

 

Thanks in advance.

Also, please let me know if there is anything else you need from me to fix the bug and I will fetch it for you.

You would have to talk to chickenbones, on his main thread on the minecraft forums.

We don't write NEI/CCC here. And it is a error in that code.
