Well, something went wrong when I was making my windscreen, and now I somehow managed to glitch a second sheet of reinforced glass into existence. I guess because the glass I was using to construct the screen was on the other side of where the screen would be, so the game wigged out and gave me a debug message about being unable to find the materials, before giving me the windscreen anyway. I guess it errs on the side of making stuff work, then? Either way, part of my windshield is made out of ‘The Glass That Should Not Be’, and I have some spare glass now
