These purple crystals are suppose to go away after reset, I assume. But they aren't.
I got these from DM spiced quests.
I had a few that said "dissipating, unstable" thought maybe it was something different. I think they eventually vanished after a couple resets but I might have used them.
Got them from the purple crystal mine.
I've gotten Dissipating crystals from a DM event that didn't go away as well, but the ones from the cave seem to actually dissipate.
They're the ones from a certain supply bag, yeah? I've had those too. Not that I mind having a crystal that doesn't go away.
From "Bags of Supplies" that I've given out?
Found something that may help illuminate this issue. Not sure the source of either. I believe one MAY have been from a bag gained in a Caster DM event and the other the Purple Crystal cave QA.

I believe the "Purple Crystal, dissipating" was the one I was handing out. Thanks for posting that, Vlaid.
