Ilia Iliev worked on the GTNewHorizons/GT5-Unofficial repository, focusing on refining the PCB Factory’s user interface and logic in Java. He addressed a bug where the Tier-3 hint display did not accurately reflect stack size, ensuring hints only appeared when appropriate and reducing unnecessary UI clutter. Iliev also corrected Creative Mode building behavior so that factory output matched the actual stack size, improving gameplay reliability. His work demonstrated a careful approach to game development and software engineering, emphasizing clarity and consistency in user experience. Over the month, Iliev’s targeted fix contributed to more predictable and maintainable factory mechanics.
