Why did the 1st Purchase Bonus/Daily Diamond Purchase Bonus disappear?

• 1st Purchase Bonus
• Daily Diamond Purchase Bonus

The tiles/icons/buttons for the purchase bonuses above will stop being displayed in the following situations.

1. If their campaign duration has expired.
2. If each step/goal has been cleared and each bonus reward has been claimed.

If there any items that can be claimed, but have not been, they will be sent to the Presents Box at 0:00 (Server Time) the next day.

Therefore, the icon for the 1st Purchase Bonus will disappear the day after you clear each of its steps.
