Sanctum Sprint Bug?
I dont know that has now happened to me, try support ticket
This is happening to me as well, I thought I was at the wrong NPC, but he keeps talking about the Sanctum Race. But everytime I go in, it takes me to the new PvP arena. o_O
So ANet’s Paul Belz says:
“Hey everyone, we’ve nailed down what causes this and will have a fix in a hotfix.
For now, to avoid this problem, please close the conversation with the aspect master and choose to join the game from his first conversation screen.
This choice should always send you to the sanctum sprint."
