I have developed a unique macro that will help you avoid automatic shutdown due to being in the AFK state, even when you are in the bunker. This macro is able not only to effectively prevent exit from the game, but also to independently purchase raw materials. 

For optimal performance, I strongly recommend setting the resolution to 1920 x 1080 in full-screen mode without frames. 

By default, the macro timings are configured for a fully improved hopper, but you have the option to change the time between purchases of raw materials. To do this, simply scroll down to find the setting associated with pressing the «A» key. There is a waiting parameter between pressing and releasing this key, where you can set the required interval for the constant purchase of resources or adjust it to your game tactics. 

Don't forget that this macro can be used both during development and during the production of goods. 

Before using it, I recommend that you go to the logistics computer where you purchase raw materials, and sit tightly in the chair to the right of the screen, after which activate the macro. It's also worth making sure that you have enough empty goods and raw materials in stock before that. Enjoy using it!
