Save often. If there's an auto-save function then will be better, but at least I didn't find it yet. At least you can use Ctrl+S to quick save.
Just search 'Gangsters organized crime windows 10 fix' then you'll get it on the first result. You just need to copy-paste 2 small files into the game directory then everything is good to go. Tested this myself. The link: https://github.com/elishacloud/dxwrapper/wiki/Gangsters-Organized-Crime
