zambrey: If specific floor doesn't show here it means you hadn't store anything on this floor on previous runs on that difficulty.
IronArcturus: So the only way to "keep" the floors is to store random items?
Update: I just got to the 10th floor again, saved some items in the locker, and now the menu choice is finally back! Thanks! :)
Cool, glad I could help :)
Personally I don't use this feature so I don't see this popup at all :) I prefer hardcore style with basic gear.
I finished Insane Seeker two days ago and it was very intense, especially around 30 floor.
Then I finally found the Sword of the Stars which is OP as hell and managed to win without much trouble.
Good luck, you might need it in the Pit :)
