So because I'm so forgetful, I forgot to extend my Jett's core aura by 30 days. As a result, it reset itself, however:
- It automatically ranked down from gold to purple rank,
- Using the 300NX cubes ranked it down to the lowest possible rank,
- And using a 1300NX cube, which clearly states that it doesn't affect the ranks somehow ranked it back up to the green tier, and another cube ranked it up to the purple tier
In sum, it seems to me like the Jett Core Aura and its Cash related items are glitched, and the 300 NX cubes should NOT be used.
And now, I've lost over 60k NX just trying to get this thing back to Gold rank
