Unless this is actually a bug , the current Urgent Quest schedule was incorrect. Perhaps the color coding was goofed up? Here it says the Urgent Quest: "Gone With the Wind and Rain" is scheduled to be after the concert at 7:30pm PDT and Wed the 27th. However, after the concert it was announced that Dark Falz is approaching the ARKS fleet.
This is somewhat bothersome for alliances that form large MPAs. This isn't the first schedule mistake either. Please double check the schedule to make sure that the future Urgent Quests are correct!
