Title.

Here's a screenshot proving I did grant myself the permission to build up to 100 floors (I am gorilla):


Here's a GIF demonstration of my issue:

Any help is appreciated

Weird phenomenon: on that specific foundation (even if I completely replace it), I can't build the elevator to higher than 6 floors, but on another floor I can build higher than 6 floors. I don't know what gives.

Any clue to how this may be?
