Can anyone explain the way the gift box leveling up progression works? I know there are two growth bars one is purple and one is light blue. At first it seems like the purple bar is moving then it stops and you have to fill the light blue. That bar is 2 million (at least the level where my guild is at) and you have to fill that before the purple bar moves again. But it only moves a little and then you it freezes again and you have to fill another 2 million on the blue bar. I don't understand how this work and how to calculate it it. Can someone explain how this work and how i know how far until the next gift level?
Likewise the gift box types seem random as well from common to epic, can this be explained?
