Ali Lesha focused on improving the stability of the Black Market feature in the-Astra/Hot-Potato, addressing a critical startup crash that occurred when the reroll cost was not properly initialized. Using Lua and leveraging skills in bug fixing and game development, Ali implemented defensive initialization logic to ensure the reroll cost always starts at a valid value or zero. This targeted fix eliminated crash scenarios under specific starting conditions, enhancing the reliability and user experience during first launch. While no new features were added, the work provided a more robust foundation for future enhancements to the Black Market system.
