QuoteRedstone, Gunpowder, eventually even a fractal of a diamond
Well... maybe you included this for future releases, but we have neither redstone, nor gunpowder or fractal diamonds.
And Alblaka said that there are 16 crops out for discovery. Well... maybe this is more or less a question of wording, because "discovery" would exclude plants already existing like wheat and reeds.
If 16 is the number for all possible plants on cropsticks (including the already known vanilla-crops) than we already figured out that only one is left. But since Reed, Wheat, Pumpkin, Melons and both flowers are already existing there could be also 7 plants left.
