When looking up the uses of any of the integrated gate (eg: Emerald And gate with light sensor), it produces a ClassCastException, attempting to cast a null to ItemStack. I tested this both on FTB's Infinity Evolved Skyblock v1.1.0 and an instance with just NEI, CCC, buildcraft, and buildcraft-compat
