Crafting bulk seeds results in extremely high yields

Requesting large batch amounts of Seeds on the Mortar Station yields results far higher than expected. With Farm card running & an attached Refined Farming Augment, Seed output is quadrupled.

For example, requested 96 Seeds from the Mortar Station (32 raw materials). With the Augment, expected 134. Received 264.

So on top of the doubling pre-craft, the yield is multiplied 2.75 times instead of 1.4.

Strangely, moving the Augment away resulted in something bafflingly different. Requested 96 seeds. Without the augment expected 96 seeds. Received 270.
