I've been cross breeding on my SP world and server for a while now, and have gotten quite a few new plants that i've figured out just fine. I can harvest them, replant them, cropnalyze them, etc., with ease. However, I've just grown ferrus and what i believe to be redwheat as well, but whenever I right-click to harvest them, they don't drop anything, they just look like I've harvested them. I've done it quite a few times, so it can't just be a bad drop. Please help?
