I found what is most likely an unintentional event when I started in a lab scenario where once I reached the ground floor with the doors and turret I am still allowed to use the stairs to climb up yet again onto the roof of the complex and leave right away by just climbing over the wall. This has happened consistently across a number of characters and worlds and seems to happen every time so far.
I think I read somewhere this is a bug due to using z levels and basically happens because there is no ceiling.
