If you are on mobile, the sphinx might not work. If it happens, just reload the page, and everything will be back to normal. If something does NOT look as it is supposed to, reload the web page (talking about the sphinx). Click on what you want to build, then click where you want to build it. Don't build until the previous construction is done being built.
THANKS TO @dmino40 AND @duconlatristesse FOR THE DESIGN AND THE DESIGN CODING (3D).
