So, it's been a few months since I last played, but the last time I played there was an option in the Cave of Memories to return to the last accessed floor via the elevator. I remember that this option only existed per play session, so if I exited the game, I had to start the group of 25 floors over. But this option doesn't seem to exist anymore? Was it removed?

There’s an elevator for every 25 floors until 125 then no more elevators and it’s endless. If you don’t make it to twenty five floors then you start over or go to the previous 25

I know, but there used to be an additional option called "Last reached" in the elevator. I definitely didn't imagine it because I found at least two bug report threads with a screenshot showing this option. But it is no longer showing up for me.
