I'm trying to complete Tutorial #5 Crusher: Shredding & Printing, but I can't complete the very first phase of crushing the large boulder into smaller rocks. I've used the crusher to break apart the boulder into only chunks that say Unknown Rock: Ready to Load, but I'm stuck in the phase telling me to break down the boulder. Am I mis-interpreting the instuctions? Am I supposed to crush all the rock chunks until I can't see any rocks at all?
