Worked on stabilizing coal production workflows in the TerraFirmaGreg-Team/Modpack-Modern repository, focusing on resolving inconsistencies in recipe outputs and durations. Addressed a key bug by removing a duplicate coal recipe and standardizing input quantities, which improved the accuracy of coke production rates and maintained gameplay balance. Utilized JavaScript for data modeling within recipe files and applied rate-scaling mathematics to ensure production curves matched intended automation flows. Collaborated with other mod developers to review and merge changes, emphasizing clear documentation and maintainable code. The work enhanced the reliability of production chains and reduced the risk of future balance issues in the modpack.
