Jaded Amaranthus doesn't seem to be spawning mystical flowers at all. No errors or anything showing up in the logs. Placed it down, tried both dirt and grass around it, full mana pool near it, linked. Flower shows it is linked correctly to the mana pool (and it is definitely close enough), and even shows full mana. No flowers appear around it. Used it numerous times before, so pretty sure I'm not doing anything wrong here.

Using build 302 (latest as of this time), Minecraft 1.9, along with the recommended Forge version of 12.16.1.1887. Let me know if you need anything else.
