Anytime I put a tuned crystal into a radio, it just gives me that error.

Im not sure what is wrong, only thing I can see is that the developers of TPPI (Modpack) have done something.

I've tested most of them (because of how infuriating it is to find a villager with the trade) and all give me the same error.

Also, a minor thing; could you add a way to get the crystals in multiplayer?
