Why don’t I see the Limited-Time Series on my account?

Limited-Time Series are only available during their active window. If the timer has ended, the series will no longer appear.

Where are my rewards for completing a set? 

Set completion rewards and the Grand Prize are granted upon completion. If you think you missed something, try restarting the game and checking your latest rewards/receipts history (where available).

Are Limited-Time Series always available?

No. Limited-Time Series run on a schedule and appear only during specific windows.
