State of War - quest is "stuck" - SOLUTION
One of the objectives requires you to capture multiple territories (Oberland Station, Forest Grove Marsh, Federal Ration Stockpile, Lexington, and Fort Hagen Satellite Array). After doing so, sometimes the quest markers remain, and it may seem like the quest is stuck.
SOLUTION: Launch an additional assault at any territory after you have assaulted each of these locations. This should allow things to recalculate and trigger the next part of the quest objective.
