- Added a startup warning when the Base Package is stored inside the XPlane Map Enhancement installation folder, helping prevent map data from being deleted during installation or updates. New Base Package selections inside the installation folder are now rejected.
- 当底包位于 XPlane Map Enhancement 程序安装目录中时，启动时会显示警告，避免安装或升级时误删地图数据；新选择的底包路径若位于程序安装目录中，也会被阻止使用。
