The mission Brainiac Ascension directs us to an empty spot on the Watchtower where a kiosk should be.

I'm absolutely shocked this isn't getting more attention. I've seen player after player go to the spot in the WT just to find out it's not there and then sit around not knowing what to do.
"Science Spire Kiosk is Missing in the Watchtower. The Marker on the Map is there but NOT the Kiosk" Yup. This.
FYI: from today's update notes: Removing Brainiac Ascension mission. That mission was for an early version of the Science Spire that was never fully built.
