King's Treasure Dice validity

Hi Admin,

Just a query on the ongoing King's Treasure event. Does the unrolled Black & Gold dice snowball over to the next event? I have completed the 30 loops and have some left over dices which i intend to use next month. The in-game event rules only mentions that the tokens can be used in the next event but doesn't mention if the unused dice expires when the current event is over. Please assist to clarify with the developers. Thanks & have a good day.
