"a crystaline enforcer" in Skyshrine might be mispelled (crystalline ?) and drops ToV items like Raw Velium Ore and Velium Impacted Raw Diamond, as well as the expected Restless Velium Tainted Diamond.
This is also happening in Sleeper's Tomb (non-instanced.) Doing progression this past Friday, I looted a ToV-era Velium Impacted Raw Diamond from "a foreboding sentry," while groupmates looted Raw Velium Ore from "a crystalline sentry" and "an iridescent caretaker" - who also drops the new CoV TS items as mentioned above. We all mentioned it as seeming odd, since no one would really want the older TS items in the final zone of the new expansion, really.
I was doing one of the partisan tasks in WW yesterday (the one with the dracoliches) and got a Raw Velium Ore off of one.
