Describe the bug

Certain recipes are not being recognized anymore whilst still being in JEI. One example would be from Ars Elemental all of the 'upgraded' armor (shown in screenshots). Another example would be from Extended AE, recipes from the circuit slicer (specifically the silicon recipe)

Steps to reproduce

1. Replicate the recipe requirements from JEI
2. Be disappointed that it does in fact not work as shown

Expected behaviour

Crafting of to start, inputs to be taken, and output to be given

Screenshots

Additional information

I haven't had time to test if there are any other broken recipes, but I can only assume there are since these two mods are so different from each other that it feels as if the recipes in the modpack have been altered.

Is there any update on this issue?

Mega Torch also not craftable, reporting "No recipe found", my pedestals flash purple above them, so it found them, but the three diamonds and three regular torches don't count for some reason.

**edit I think I found the reason. JEI doesn't list Source as a requirement for the Mega Torch, but the craft worked when I had a source jar nearby.
