Some bad news to report, the maintenance will not be happening tomorrow. We thought we were very close to having patch ready to go but when we were in the final testing stage it was determined there was an issue that would cause a large number of players to be kicked to character select regularly. Obviously, that put the brakes on 5.9.2a for tomorrow.
The team has already begun working on getting this addressed and to get a new patch ready. The new estimated timing for maintenance will be Tuesday, 8/21.
Thank you again for your continued patience.
