When trying to make electric light AE2 pattern, the pattern uses Silicon Ingot from Vulpes Library (#4972/3), instead of the silicon wafers from gregtech. Nothing breaking, I just have to swap out the Silicon ingot for the wafer, but I imagine it is not intended.
To reproduce:

1. Use JEI input for ME Pattern terminal for the electric light.
2. Pattern becomes the wrong one.

My guess would be that it's probably a side effect of being the first item registered to an ore dictionary entry. We can look into it.

While it is annoying at least it's just a matter of correcting the recipe to use the right variation of ingredients, if you want to do on-demand recursive crafting.

It seems that we do disable that particular item in _oreDict.zs so I'm surprised that JEI is still considering it in the recipe click-in.

The recipe is the vanilla one though, so we'd probably have to replace it with an identical custom recipe to make it suggest wafers instead.
