Mayan Awakening Shards

Mayan Awakening Shards allegedly now drop in the Mayan Dungeon. I haven't seen any yet, though. Anyone else? Any idea what rate they drop?

I think they are in app purchase only. Didn’t see it mentioned they drop in any tuning notes

That's what I thought, but then I saw this.

Attachment 9480

it was mentioned in february tunning notes

I'm pretty sure it drops, I have 14 Mayan Awakening Shards and 100% sure I haven't spent money on them.
