             <li><strong>[Fix &mdash; Map Search DB]</strong> Resolved a critical database issue where objects and NPCs searched via Advanced Search failed to display all available spawn locations.
                 <ul>
                     <li><strong>Override Prioritization</strong>: Refactored <code>QuestieDB:GetObject</code>, <code>GetNPC</code>, and <code>GetItem</code> to prioritize manual corrections (overrides) over the compiled database. This ensures human-verified data is always used when available.</li>
+                    <li><strong>Correction Loader Fix</strong>: Resolved a fundamental flaw in the correction system where WotLK-specific object fixes were being written to the binary database companion table (<code>objectData</code>) instead of the active override table (<code>objectDataOverrides</code>), causing overrides to be ignored by the rendering engine.</li>
                     <li><strong>Data Compatibility</strong>: Hardened the database engine to support both integer and string-based indexing, preventing <code>nil</code> errors on legacy clients while maintaining performance.</li>
                 </ul>
             </li>
             <li><strong>[Fix &mdash; Object Spawn Data]</strong> Restored missing "Blood of Heroes" (ID 176213) spawn locations.
                 <ul>
+                    <li><strong>Override Migration</strong>: Restructured the 150+ verified spawn locations to use the direct override path, ensuring they correctly render for all factions in Plaguelands on WotLK servers.</li>
                     <li><strong>Data Merge</strong>: Integrated 150+ verified spawn locations from both the Classic database and Wowhead scraping into the WotLK module.</li>
                     <li><strong>Deduplication</strong>: Sanitized coordinate data to remove duplicate pins, providing a cleaner map interface for high-density spawns in Plaguelands.</li>
                 </ul>
