When we go to start the Scratch Sentry Defense Guild Mission, another guild’s flag is displayed and no event is ongoing. We tried guesting out of Ferguson’s Crossing to Jade Quarry and Dragonbrand and both servers are having the same issue. When you interact to start the mission you get the error “An officer must start this mission.”
It looks like when some previous guild starts the mission it bugs it out for future players. There is no way to abandon the guild mission or fail it because it cannot be started.
EDIT: We’ve tried guesting to every other server and they all have the same problem. We were trying to find one on which to fail the event with no luck. We’re stuck for 5 hours now unable to progress Challenge.
