During June 2025, Qzwxsaedc1 focused on improving configuration management for the GregTech-Odyssey repository by addressing server-pack contamination issues. They implemented a targeted change in the TOML configuration files for BoccHUD and MaFgLib, updating the 'side' attribute from 'both' to 'client' to ensure these mods are only included in client environments. This adjustment, using skills in mod development and configuration management, reduced the risk of client-only mods being packaged with server modpacks. The work demonstrated careful attention to deployment boundaries, resulting in more stable and maintainable server deployments without introducing new features but resolving a key packaging bug.
