Crash Report: http://pastebin.com/TGaYxmTK

So as a description of what happened, I was updating the pack I am working on, and everything was working fine. After committing the build to the pack manager and downloading a fresh copy of the pack With HEE installed it give me this error.

Extra Info that will probably not help:
There are no config changes between the versions and same with the IDs

I'll send you a debug version of 1.6.3 later, which outputs all found recipes.

Actually, you may have it already.
