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.
