Got it! Thank you so much.
I'll try We are allowed to receive 12 crystals per day from our neighbors. Each of those crystals has a rolling 24hr clock attached. The crystals we earn in playing scenes don't count towards that limit. Those are random drops on top of our limit. The game controls those drops by using a random drop rate programming code. I don't know what the code equals out to, but it's likely the same code used for collection pieces just at a different rate.
