Cutscene for quest hides Levequest status, timer, etc.
I don't know if this was already reported.
I started the Levequest "Get to the Copper," and still had the quest "Golden Sacrifices" active, and when I went to the CS spot in Thanalan (North of Camp Blackbrush) and the CS activated with the Levequest active.
After the CS, the information for the levequest (the card icon, the timer, and progress) all disappeared, and the music had changed to the normal tune of Thanalan.
I was able to continue the levequest, and the graphics for it returned after I finished mining the first spot. I was able to complete the levequest, however.
