Revenge of Cronus

Missing Boss Battles will return to ZERO and locked again with an orange hex . Players can still take missing Boss Battles and make corrections to those unmastered < 70%. Players must request the newly mastered Boss be unlocked in order to move ahead. Reasons?
Grades will be reflected more accurately. Players were told this would happen, given a chance to catch up, and now time is up. Players all caught up are not impacted by this.
