I’ve noticed that sometimes, when the vehicle trim is completed, when going back to the engine and modifying any parameters the engine graphs and charts don’t update until I move to the vehicle trim tab and back to the engine tab at the bottom of the screen. This takes place in the sandbox vehicle editor. It only ever happens when the vehicle trim is complete, but even still it doesn’t always happen. When the graphs are failing to update, the rotating Automation logo appears but just rotates indefinitely. Restarting Automation completely can fix it.
In addition to this, the game registers as “still running” on Steam long after exiting the game using the menu. The only way to get around this is to close the game via Steam as there are no obvious background processes from Automation showing in Task Manager.
