 - Fixed an issue where some units crashed after the deployment transformation.
 - Fixed the bug that AlphaImage remained after unit entered tunnel.
 - Fixed an issue where Ares' `Convert.Deploy` triggers repeatedly when the unit is turning or moving.
+- The game now automatically changes save file name from `SAVEGAME.NET` to `SVGM_XXX.NET` (where `XXX` is a number) when saving to prevent occasional overwriting of the save file when using Phobos with XNA CnCNet Client and saving too frequently.
+  - 1000 save files are supported, from `SVGM_000.NET` to `SVGM_999.NET`. When the limit is reached, the game will overwrite the latest save file.
+  - The previous `SVGM_XXX.NET` files are cleaned up before first copy if it's a new game, otherwise the highest numbered `SVGM_XXX.NET` file is found and the index is incremented, if possible.
+  - The game also automatically copies `spawn.ini` to the save folder as `spawnSG.ini` when saving a game.
