Update 2/23, 10:30am PST
The redemption panel will be back up later today and open for 3 more days for redemption of Broken Hearts. Broken Hearts can still be accepted. However, they will no longer drop from jobs/fights/robs and can no longer be sent via free gifts or posted on walls.
A small number of accounts with Broken Hearts (or redeemed items) that exceeded the free limits will have the quantities corrected.
