Not sure if this is a bug or intentional, but the pylon will not harvest sourceberries (from Ars Nouveau). It will harvest other crops without a problem, so it's not the way I have the pylon set up. Berries are planted on Rich Soil (from Farmer's Delight mod) but I get the same result when planted on farmland.
