Score Balance Adjustment - Chapter7-3 Glacier tactical island

It has been less than 24 hours since the update, and there is a possibility that it will be restored later, but currently I feel that the balance of Sunstone rewards in Chapter7-3 is a bit unbalanced, so I will make the following adjustments.
Diamond-25,000,000 -> 15,000,000
Overscore-2,500,000 -> 1,500,000

Please note that the Sunstone earned will not be updated unless the score is updated.
