I stated playing today and unfortunately am stuck in the tutorial. I'm unable to make the signal numbers move by pressing E and scrolling the mouse wheel. Most of the time it just makes me scroll through the stuff in my hotbar. I've been at it for about half an hour now and am getting frustrated. I managed to make it work very briefly but I have no idea how I did it, though I was following the instructions as far as I know. I'll keep at it in the meantime. Any help is appreciated!
