Clicking on the quest again will deactivate it. The quest will stop tracking you for the objective, but it will save its progress until you activate it again. This is important because you can only have 5 quests activated at any time. * If you have completed Quest D18, you can activate the Headquarters Personnel item obtained from the quest to permanently increase the active quest limit to 6. When you complete the quest, the icon on the right will turn blue. Click on it to claim your rewards.
