Where did my vault go? Are moons dead?

Oh no!!! I just started receiving some moons for participating in the sub. I loved them. I cherished every moon that was airdropped into my vault each month. Sadly I was not good at farming them. So I mostly just creep the sub and make comments. Recently however, I got a few good comments and my karma went crazy relatively speaking. I would never post random things just to reap the karma. I’m against that entirely. But I do love seeing those moons stack up. Please tell me they are still a thing. I really don’t know much even about them. But I like em. Where are my moons guys? Wen does moons moon?
