Synthesizing items from radioactive materials doesn't work

[PaladinWho]

Not entirely certain what causes it, but I believe because of how radioactive half life times work, it causes the chemical synthesizer to not be able to create items from radioactive materials. For example, when attempting to synthesize a nether star, despite the fact I had three different stacks of 16 copernicium in the machine, all other related materials, as well as supplied with enough power, it simply wouldn't craft.

The copernicium in the crafting table area seemed to be counting down its half life as well
