if you don't know, i have recently discovered a way to go to an archive page.
1. write in your search engine *wayback machine*
2. once you're in the wayback machine, write in the little box in the middle beno.uk/askyscrapersim/creator/
3. click enter, and then you will see a timeline, go to 2021 and scroll down to the working build aka July 28th 2021 then finally click that button.
or click this link or copy the link :
