When the Mystical Agriculture mod config for secondary seeds on harvest = true, harvesting Earth essence plants will not produce extra seeds, whereas the counterparts Water and Fire do.

ATM 0.1.10, haven't seen a report for this yet. unsure if its a mystical agriculture issue or something is conflicting.

Sample Size - 128x mystical fertilizer on earth Earth, water, fire plants on inferium farmland.
Results - Earth Seeds - 0, Water seeds- 30+, Fire Seeds 30+

This also seems to be affecting Ice essence plants as well.
