Quick plant modding question: I'm trying to add saffron and I almost have it right but for some reason when the dwarves harvest it from a field they grab both the plant (crocus) and the "leaves" (saffron threads). I basically copied the Quarry Bush raws so I thought it would behave like a quarry bush, where they harvest ONLY the plant and then use up the plant processing the leaves to a bag. Does anyone know how I can make them not produce "leaves" when they harvest the plant? (the biome being underground is just to make them easier to test)
