Thanks David, the patch saved me from starting a new game.

The programmer has prepared a special version 6.4.03B for you for fixing this rare bug.

To apply the patch, please extract the attached RAR file to your post-release Beta version of Capitalism Lab program folder. You can open your Capitalism Lab program folder by right-clicking on the Capitalism Lab Post-release Beta game icon and select “Properties”, then select “Open File Location” to open the folder.
