During December 2025, Reh Guedes focused on resolving a dialogue and quest interaction bug in the rathena/rathena repository, specifically targeting the Rock Ridge NPC scripts. By analyzing and updating the scripting logic, Reh improved dialogue clarity and enhanced the reliability of quest progression, directly addressing issue #9686. The work involved careful adjustments to NPC interaction flows using scripting and text-based configuration, ensuring that players experienced fewer interruptions and less confusion during gameplay. Although the contribution was limited to a single bug fix, the targeted approach demonstrated attention to detail in game development and provided a stable, traceable solution for future maintenance.
