I had the same problem as you last night. But I managed to unlock it by opening every quest that I could on the left side of the map. I think one of your other priorities in this event as you try and complete the ACTS is to open as many quests as you can, since they tend to open locked quests. BTW if you manage for example killed a specific type of mob 100 times before opening the mission that requires you to do so, the game will register that mission as complete the moment that mission is unlocked.
