A change has been published about the explorations and crystal limitations.
- You can now explore once or twice per 24 hours and not per day
- You can now get 1 crystal per 24 hours and not per day
These changes are intended to put all players at the same level regardless of their time zone, indeed limiting these actions per day with reset to 0 at midnight French time provoked bugs and inconsistencies.
Thank you for your understanding and have a nice time!
