Same problem as Skielsthear's: in the "Storm Tracking" mission, after you protect Blish and you are instructed to run from the storm, the instance boundaries update visually on the minimap, but appear to remain the same as the ones during the protection event. As a result, following the green arrow/wings sprite gets you killed; retrying starts the event, but you keep dying as soon as you approach the first building in front of you, with the message saying you're leaving the instance boundaries. EDIT: It seems to be the case that the playable area is erased entirely the first time you get the message. Even if you turn backwards and jump to where you just came from, the game kills you for going outside the playable area.
