GA not correctly increasing with Masterwork

Hey,
there is something really wrong with how Greater Affixes increase when Masterworking.
My Gloves have a Greater Affix crit.

According to the Game the Affixes increase as follows if u hit the 25 every fourth on the same stat:
Level=L L1=5% L2=5% L3=5% L4=25% L5=5% L6=5% L7=5% L8=25% L9=5% L10=5% L11= 5% L12=25%

Back to my Gloves with a GA on crit 12%
They are Masterworklevel 8
Thats means they increased as follows:
12 * 0,05 = 0,6 12 * 0,25= 3

0,6+0,6+0,6+3+0,6+0,6+0,6+3= 1,8+3+1,8+3=9,6
So it should be 12+9,6= 21,6
But its at 18,4%
The same thing also applys to my amulet.
Somehow GA are not increasing the way they should. Please fix this.

Not a bug. It uses the base affix value, not the GA one.

So it is a bug, there is no mention in description it will use base value or anything like that. Why should it use base value in the first place? It does not make any sense. It is just a lazy coding.

For balancing purposes? So GA isn’t even more OP than it is now? Lots of factors go into how they decide to code things that aren’t described in game.

Mate this game has so many bugs that at this point it’s 99,9% likely that GA masterworking is bugged XD

Before it’s comfirmed by devs if it is intended behavior please stop spreading misinformation that current behavior of GA masterworking is inteded nor it is for balancing purposes - 'cos it’s not it’s just yours delusions.

Bugged bash tamper is also there for balancing purpose? Because barb is so weak that additive bash (+ sign in tamper description) works as a multiplicative tamper?
