Greetings Summoners!

We are aware that some players have received Guild Raid Season 1 reward on April 15 20:00 PST. The Guild Raid Season 1 reward was not intended and awarded by error. We are currently correcting the issue and will send out the appropriate Guild Raid Season 2 reward during today's maintenance from April 18 22:00 - April 19 4:00 PST. All claimed rewards will be removed from inventory accordingly.

Thank you for your patience and consideration in the matter.

~ Brave Frontier Global Team
