Hi I have upgraded my shaft M0 full 20/20 but the system did not give me the M1 f
or free and I had not yet reached the rank to buy it so i do not understand why it would not give me for free
As you can see, it costs you 0 crystals to purchase the shaft but as you already said you didn't reach the rank to unlock the m1 modification yet. So, you need to rank up and once you reach the needed rank to unlock the m1 modification,click on the "Buy M1" button and you'll have it. You don't need to worry as your current shaft M0 has the same characteristics of the M1 modification as you fully microupgrated it.
