When a theme has too many rooms down, unfortunately we place it on hold until we can re-build it. However, for other hunts who are only lightly touched we always provide excess treasure & for the few pieces down we place a sticker within the hunt next to the treasure that's not available. Unfortunately on weekdays about 10% of alternating departments of the Louvre is closed daily, for instance:
● Monday & Wednesdays: Near Eastern Antiquities, Middle Ages
● Thursday: French Sculpture
● Friday: Egyptian Antiquities
● Weekends: All treasures available, all departments open
