In June 2025, Abyssien developed the Chemical Bath Washing Filter Tagging feature for the GregTech-Modern repository, focusing on enhancing in-game item processing. By introducing a new 'Liquid' tag linked to material properties, Abyssien enabled more granular filtering and control over which items can be washed, supporting future property-driven automation. The implementation leveraged Java and mod development skills, with careful attention to API integration to ensure maintainability and extensibility. No major bugs were reported during this period, reflecting a focus on code quality and robust feature delivery. The work laid a solid foundation for further enhancements in automated item processing.
