Hi Holotable Heroes,
We experienced some issues with the sign up period for the March 3rd Grand Arena overlapping with the Review period of the previous Grand Arena, . We will be rescheduling this event to start 3/5 and allow players the full time to join from 3/5/19 - 3/6/19 (Starting at 2:00pm Pacific/20:00 UTC).
Please note that the Grand Arena starting later today will be canceled with an update shortly and you do not need to set defenses. In order to accommodate this change, the Review period for this event will be 16 hours long instead of the usual 24 hours.
