New World v6.4.1 Crafting Crash

[Voidwalker227]

While creating an Aqueous Accumulator I shift-clicked the recipe for a bucket (iron ingots) into a crafting table via NEI. Instead of the recipe showing up the internal server shut down and I was given a crash report. I've uploaded the report, but upon reloading I did not experience a crash when I once again tried the same thing.

This is to rule out any issues with your setup.
Please attempt to launch the modpack, and open a new world save to make sure the setup is correct.
Now, continue on to check your previous saves, changes to the pack, textures, etc. until you're able to reproduce the error with the clean setup.

When the error has been repeated, please post your complete client-side (launcher) console log in debug-mode to pastebin.com and link your paste URL here.

Though, if it's not repeatable, then it may have just been a fluke.
