Worked on the Wynntils/Wynntils repository to enhance stability and user experience in the Wynncraft integration, focusing on backend development with Java and Regex. Addressed two critical bugs by improving chat tab handling to prevent crashes when the chat tabs list is empty, thereby refining chat UX and reducing user disruptions. Updated tooltip parsing logic to support the latest Wynncraft format, ensuring tooltips render accurately even when rarity color is undefined. Maintained high code quality by adhering to CI formatting standards, contributing to the maintainability and consistency of the codebase. No new features were added during this period, emphasizing reliability improvements.
