Is the Rebirth Crystal timer broken or am I just not understanding what "every 7 hours" means?
According to all the official notes, the crystal is claimable "every 7 hours." I claimed 2 so far, and after I claim the crystal, the timer says I have 7 hours from the time I claimed the crystal. It's not every 7 hours.
From the website at

7-Hour Login Crystal
Every 7-Hours a Login Crystal will be claimable
Two rewards per Crystal – one that is Champions or Rank-Up materials, the other will be a consumable, such as a potion or revive
Other timed crystals work on a "global" timer, where if I claim the crystal 5 minutes before the refresh I can claim the next crystal five minutes later. Is this not the case with this one?
