Uncraftable Item

[ItsWishSnipes]

The Flux-infused Jetplate is not craftable. Not sure if its a SimplyJetpacks-2 issue, related to charge of items used to craft or if another mod is interfering. Here is a screenshot of the items being crafted. I am running FTB Revelation version 3.2.0 as well as the latest version of SimplyJetpacks-2. I have added 2 mods of my own being "ChickenChunks" and the "EnergyConverters" mod. Thanks you and I will check frequently for your response!

Looking at the image above I think your Resonant Flux Pack is missing its Invar Plating - the version used in that crafting recipe is the armoured version. Try installing the plating then try the above recipe again.

Both the Jetpack and Fluxpack need to be fully armored for the recipe.
