Ok, so this to me is the dumbest thing ever.
Why do they even bother to visually display the upgrade chances if it’s all a scam. It happened to me like 3-4 times already.
It also fails a hell of a lot at 90%, but at least you think to yourself that you are unlucky, there’s still a 10% chance to fail.
But at 100% chance, fail… this is just stupid, devs need to learn some math.
