General Bug Fixes
-Fixed an issue where [OLD] Goldwork of Attack and [OLD] Goldwork of Magic Attack (D/C/B/A/A+) provided a lower bonus than expected.

Ultimate Jewel Changes
-Jewels socketed into Soul-Linked or Account-Linked weapons before the maintenance will become tradable when extracted using Jewel Tweezers after the maintenance.
-Soul-Linked or Account-Linked jewels will retain their original binding status even after being socketed into a weapon and subsequently extracted using Jewel Tweezers.
-If a Soul-Linked or Account-Linked jewel is socketed into a tradable weapon, the weapon will inherit the jewel’s binding status until the jewel is removed.
