Hi Holotable Heroes,
Before we restarted the first Grand Arena Exhibition, some players spent crystals to refresh their Fleet Arena in order to complete one of the Championship feats. All eligible Championship players who used crystals to refresh Fleet Arena between the start of the event and the restart will be sent the spent crystals along with an inbox message explaining the issue. We are planning for an update to send these crystals out sometime next week, but we will let you know closer to the release.
This took longer than we expected to solve so thank you for your patience. See you on the holotables!
