First of all, keep up the good work!
I’ve noticed when building a tower with internal stairs, that the workers don’t build the walls within the section of the tower where the stairs are located. I’d love to place a screendump, but “new users can’t upload images”
First of all, welcome to the Discourse! (I beat @SteveAdamo to saying this! ^^)
You can upload the picture to something like Imgur and post the link. Someone of the mods will then surely edit the images into your original post.
Great suggestion image can be found here: Imgur: The magic of the Internet
Notice the highest section of the wall is missing, but the roof is completed. The workers still remove the scaffolding in the end.
