Regarding Daily Quest Heart Rewards

(Summary at the end) 1. A discussion arose on Discord about heart rewards differing between players (by 개트롤). 2. Checked with others on Discord, and it showed 80 hearts. 3. However, when I checked this morning, it was 30. 4. Now, when I check, it has changed to 80. 5. I thought I might have misread, but checking my heart history confirmed I received 30. 6. Similarly, the 7-day consecutive challenge reward also increased (100 -> 300). Conclusion: The rewards for daily missions have increased. The rewards for completing 3 missions and the 7-day consecutive challenge have definitely gone up. The rewards for individual quests seem to remain the same (10-30).
