^ Welcome back. The building's glass transitions to yellow cladding at the top. What you're seeing is permanent. They're working from the top down. Also, they've not topped out yet and have 6 more frustums, or 726 feet to go. There is a detailed post about this if you search 200-400 posts back in the thread.
JK. Yellow formwork should be gone within a month and core topped out a week or two ago.
