10.1.2

• Updated seasonal map effects to follow astronomical seasonal boundaries in both hemispheres, with smooth transitions around season changes.
• Added a persistent Season Override that lets you choose a season while running, or return to Auto to follow the simulator date. Clear cached areas and reload scenery after changing it to update previously loaded areas.

• 调整季节地图效果切换时机，按春分、夏至、秋分、冬至判定南北半球季节，并在换季日前后平滑过渡。
• 新增可保存的季节覆盖：可在运行中固定选择季节，或切回自动模式继续跟随模拟器日期。切换后请清理旧缓存并重新加载场景，以更新已加载区域。
