Would love some independent verification on this. Might be chance, but...
I turned in artifacts today and got a Pristine artifact. (Two in a row, yay!)
However, when I used the crates to buy Tol'vir artifacts, an interesting thing happened. All three crates contained not only Tol'vir fragments, but a Tol'vir Heiroglyphic as well. I've probably turned in 100 of these crates to date and never seen a single item like that.
Is this an existing behavior that I just got wild luck streaks on, or is this an undocumented change?
