During June 2025, work focused on developing the Chemical Bath Washing Filter Tagging feature for the GregTech-Modern repository. This involved implementing a new 'Liquid' tag in Java, tightly integrated with material properties to enable more granular in-game filtering and item processing. By leveraging skills in API integration and mod development, the solution allowed for precise control over which items could be washed, supporting property-driven automation and laying the foundation for future enhancements. No major bugs were reported during this period, reflecting an emphasis on code quality and maintainability while delivering a targeted feature that enhances gameplay mechanics and mod extensibility.
