Since I accidentally destroyed my save file while modding...
I started a new save, and starting on the 5-floor short runs. However, when I accidentally used that Skip Floor consumable on 5F...
The floor theme, enemies, and floor count is 6. However, the floor boss is Warden, and when I died (also accidentally... Got to keep track of my energy, uh), the final screen says Floor 5 of 5.
So I guess it's a bug. Is it?
