Contemporary Crystals

XxBLACKCRyUSxX

I know there were three sets of Contemporary Crystals under the Special tab. I can see the “Collector Contemporary Crystals” and I can see the “Cavalier Contemporary Crystals,” but I’m missing the other set. I had 12,000 shards that just vanished. Has anyone had this issue?

Were they the last month ones?
The shards disappear if you don't turn them into crystals every month.
