During September 2025, Telvayne contributed to the Vanderlin-Tales-Of-Wine/Vanderlin repository by addressing a bug affecting hair color rendering in mirrors within the game. Using DM and leveraging skills in bug fixing and game development, Telvayne implemented a targeted solution that preprocesses color values by prepending a '#' character, ensuring accurate color display and resolving an issue where colors defaulted to black. This update improved visual consistency for player customization across mirrored surfaces. While the facial hair color adjustment remains partially unresolved, Telvayne documented a workaround to minimize user impact, demonstrating a methodical approach and clear code traceability in the process.
