I am asking because I've already cleared floors 1-50 solo.
No way to know until it's actually up, but if you've at least still got the clear save it's possible maybe. If it's gone? Not likely at all. The only way it'd happen otherwise is if there's been something hidden away tracking that stuff from the start.
