Notes for update (maybe like add on bottom of changelog):
If saves failed to transfer from the previous version, please manually copy them from C:\Users\<username>\Saved Games\Close Combat 4\ to the Games folder in the root directory.
Higher resolutions might break the game design or functionality, if you wish to play at higher resolutions anyway please edit cc4.ini file.

Save files:

gameinstall\Games\Battles\*
gameinstall\Games\Save\*
