Q. I defeated the enemy with the indicated Hero but I cannot complete the quest.
Please refer to the article called 【I defeated enemies with the Hero indicated in a quest, but it is not registering as complete. Why?】.
Q. There is no button to go directly to the map in question from the quest.
Depending on the quest there may be objectives that ask you to accomplish certain tasks that are not limited to a specific map. Because you can accomplish these regardless of the map, there is no button to bring you to a specific map. Please review the objectives of the quest and take on a map of your choice to fulfill the objectives.
Also, there are some quests that require you to fulfill their objectives on certain maps. If the quest requires you to clear a specific map, you can go straight to the map in question from the quest.
