Augments yield bonus bug

Did some tests with augmentations on crafting stations with an eye on yield bonuses and got weird results!

Test 1:

Refined Masonry Bench

Blasting Machine (+40% yield)

Mining Cradle (+20% yield)

Settler Card (+20% yield)

Input: 10 Carved Stone

Yield: 12 Carved Stone

Test 2:

Refined Masonry Bench

Blasting Machine (+40% yield)

Settler Card (+20% yield)

Input: 10 Carved Stone

Yield: 12 Carved Stone

Test 3:

Refined Masonry Bench

Blasting Machine (+40% yield)

Input: 10 Carved Stone

Yield: 14 Carved Stone

Test 4:

Refined Masonry Bench

Blasting Machine (+40% yield)

Mining Cradle (+20% yield)

Input: 10 Carved Stone

Yield: 12 Carved Stone

And another testing on a different station:

Test 1:

Refined Mortar Station

Plough (+40% yield)

Simple Plant Pot (+20% yield)

Input: 10 Spice

Yield: 12 Spice

Test 2:

Refined Mortar Station

Plough (+40% yield)

Input: 10 Spice

Yield: 14 Spice

Test 3:

Refined Mortar Station

Plough (+40% yield)

Crude Beehive (+20% yield)

Input: 10 Spice

Yield: 14 Spice

While Refinement Time bonuses seems to stack until the minimum is reached, yield bonuses behave kinda weird as you can see. It seems it only takes one yield bonus into account. Which one seems to be random.

In this case it would be best to place only one yield bonus augment (the best ofc) and a Ink Making Set or a Formula Book.

I'm not on tier 3 as of now, but i guess the outcome is quite the same.

I'm quite sure this isn't working as intended.
