December 2025 monthly summary for FrostedHeart (TeamMoegMC) focused on delivering a robust Town Management UI and strengthening the GUI framework for future scalability. Key features delivered include a complete Town Manager GUI and Town Management Screen with TownManagerScreen, Mayor's Seal item, textures, vertical scrollbar, and a resident list, plus UI refinements and tab rendering that integrate with the town management workflow. UI framework enhancements relocated SnowSack from the utility package to the item package and introduced a generic TabWidget to enable wrapping of existing widgets for improved GUI composition. These efforts improve in-game administration UX, enable faster UI iterations, and establish a scalable foundation for upcoming town-management features.

December 2024 focused on refactoring the Town Resource management architecture. No user-facing features were delivered this month due to ongoing refactor work aimed at centralizing resource tracking via TownResourceHolder and TownResourceManager and introducing resource leveling. The changes are currently incomplete and not compilable, resulting in a temporary degradation of town resource tracking while the design matures. A backup commit was created to preserve the refactor intent and document the known compilation blockers, enabling safe rollback avoidance and easier continuation in a future cycle. This work establishes groundwork for scalable resource management, improves long-term maintainability, and informs future implementation decisions. Next steps include resolving compilation issues, completing integration, and validating the refactor in a feature-complete branch.
