So i had been exploring a lot at different layers and it was impossible to find some silver for the Crusher recipe, i found Copper very easily of course, Oureclase with quite easiness too but silver was impossible. Is Silver ore very rare or it doesn't spawn?

I had this problem since the first version, and i generated new chunks with the 0.0.2 version

It was a bug, as soon as possible we will release the version with the fix
