My Time Quests Rewards Are Gradually Increasing

I started Time Quests at 15,000 gems initially, but since it was my first time, I rolled with the highest multiplier and ran out of dice, failing the quest. After some time, when I went to get the next Time Quest, it had dropped to 2,000 gems. I was wondering why mine was dropping so much when others said their Time Quest rewards were going up, and I considered deleting the game. Still, I decided to at least complete one Time Quest, so I adjusted the multiplier, got the reward, and it stayed at 2,000 gems during the reset. When I went to get the next Time Quest, it had increased to 2,500 gems. 'Oh ho!' I thought, and completed the quest. Then, to get the next quest, it was 3,000 gems, then 4,000, then 5,500. After that, it was 9,000, and today I received 29,900 gems. It seems the rewards increase when you get the next quest after the reset period, where the rewards received remain. My memory isn't perfect, so I don't recall the exact digits and just rounded them roughly. It's a strange game where Time Quest rewards increase the more you play ㅋㅋ
