The real question is how many other things it's missing.
Reading the process in TFA, it's very much dependent on the comprehensiveness of the testing framework. And apparently, the tests never built a lobby in the bottom left corner...
Anything else it didn't try, is probably also not documented and not implemented.
With the growing use of AI in reverse engineering, we might need to shift our goals to more strongly verifiable ones, such as matching decompilation.
Yeah the simulation also seems to have some bugs. I saw a person get stuck waiting for an elevator for hours when all the elevators were idle. He got more and more pissed off until he eventually despawned overnight.
I agree that you need to be able to produce source code that matches the original binary before you can start porting things.
I would bet a lot.
My memory is that you could make multi-level lobbies on the first floor and you'd end up with like a grand staircase.
Edit: Apparently just pillars no staircase - https://old.reddit.com/r/SimTower/comments/1q63yvc/a_nice_to...
