Issue with items and Fuzzy NBT, maybe.

Tried to add a recipe for the Emerald Jetpack from the Iron Jetpacks mod. The Emerald Jetpack allows, as one of it's ingredients, either the Diamond Jetpack or the Platinum Jetpack. When I attempt to add this recipe, I get a message in the chat saying,

"Sorry, it seems the calculation does not converge in 1000 iterations. Please contact the developer if you think this process should have a result."

This also results in the recipe requiring 1000 times as many ingredients. If I explicitly declare I wish to use the Diamond Jetpack as an ingredient, the process works. I have included an image to show the result I am getting. Thank you for an amazing mod.
