I also fixed an error that appeared in the previous stage: the "Gherkin" was slightly tipping over to the right. Strangely I noticed it only when I put the photo on this blog. (I thought at first the photo was crooked, but it wasn't.)

Unfortunately, now I've put up this photo, I've noticed another error...
I'll let you try to find it, while I work out how to fix it.
