Worked on backend stability for the abeiro/HerikaServer project, focusing on resolving a crash related to Narrator input handling when no NPC was present. Addressed the issue by updating prompts.php to include a missing narrator_inputtext prompt entry, which prevented undefined array key errors and improved runtime reliability. Coordinated changes with recent Dev DLL updates to ensure consistent input-event processing and smoother NPC profile interactions during gameplay. Utilized PHP for backend logic and database management, with attention to robust prompt processing. Documented the fix for traceability, contributing to a more stable game development workflow and enhanced player experience during playthroughs.
