I've got this crash everytime, every version you have on curse:

Modpack is FTB Infinity Evolved 2.6 but there are no others errors than your crash. :I

fixed it.... didn't know that ftb has disabled everything but crafting and that this option would crash your mod :D^^

sorry about this, I will add a better check in the next version (the Infinity Chest will have no recipe, unfortunately).
