• An indicator of the absence of a resource has been added to all machines that extract resources (see gif).
• The save version has increased from 27 to 28, this is necessary to save new data in the indicator.

In general, I would like to explain that the version of the game consists of two separate values, the first (current) 113 is the version of the game itself, and the second (current) 28 is the version of the save game. When you need to write completely new data to the save file, then the version grows, this is necessary so that the saves fit almost any version of the game. That is, you can boot from old saves in the new version of the game, but new saves will not work with the old version of the game.
