v2.5.2 - Critical Security & Stability Update

🛡️ CRITICAL SECURITY FIX

Patched Double Purchase Item Duplication Exploit

Fixed a critical vulnerability where multiple players could purchase the same auction item simultaneously, allowing item duplication and economic exploitation.

What Was Fixed:

• Multi-purchase exploit: Players could spam-click to buy the same auction item
• Seller overpayment: Sellers received multiple payments for a single item
• Item duplication: Buyers could duplicate items through concurrent purchases
• Economic instability: Server economy could be unfairly manipulated

Technical Changes:

• Implemented Atomic Reservation Pattern - items are reserved before currency transfer
• Added Optimistic Locking - prevents concurrent purchases with version checking
• Enhanced Automatic Rollback - auctions revert to ACTIVE status if transactions fail
• Improved Thread-Safe Operations - inventory operations moved to main thread
• Added Clear Error Feedback - users receive explicit messages for failed purchases

Update Recommendation: ⚠️ IMMEDIATE UPDATE REQUIRED - This fix addresses a severe game-breaking exploit.
