FIXED Hourglass x2 Dupe During Standard Extraction

There appears to be an x2 duplication bug when purchasing an Hourglass and using it for Standard Extraction. The issue starts on Day 7 and continues on subsequent days (Day 8, Day 9, etc.).
Steps to reproduce:

1. Purchase an Hourglass.
2. Use it for Standard Extraction on Day 7.
3. Observe the resulting x2 reward.
4. Repeat the same process on subsequent days.

The extraction appears to duplicate the result, effectively creating an x2 dupe
