During November 2025, Sixez focused on improving user-facing text within the GTNewHorizons/GT-New-Horizons-Modpack repository, specifically addressing clarity in quest progression. They identified and resolved a bug in the Cobalt Brass quest description by correcting a typo using JSON configuration, ensuring that players received accurate instructions. This targeted fix, implemented through a text-only change, enhanced onboarding and reduced potential support queries by clarifying quest steps. Sixez validated the update against design references and performed QA checks to maintain messaging consistency. Their work demonstrated attention to detail in game development and modding, with a focus on quality and traceable, low-risk improvements.
