Where is Area 7? How do I check the number of stages?

Regarding Area 7, it usually refers to the seventh building site you repair as you progress through the main quest. This game often presents level counts by completing a quest list, so I recommend checking the quest notebook in the lower-left corner of the screen to track your progress. Are there any other puzzles you're encountering while managing your town?

The bottom left of the game shows the region. See if the places you've unlocked add up to 7.
