Uncertain if this is a “Bug” or if it’s as intended, but I figured I’d report it just in case.
I’ve only been down in the UW since the last patch and once before it, so I’m not sure if it’s a recent thing, but the Floor 7 Staircase was blocked by something, likely a structure or a wall. For a long while I was worried I wouldn’t be able to escape because:
1. It’s before the areas where I can obtain a lantern
2. There were no statues
3. There were no tables to make a shovel with
I was eventually able to climb up 2 floors and find a statue I had missed, thank god, but if that wasn’t there, escape truly would have been futile.

Perhaps the staircases need to always spawn in areas they can let people through? If not, then I suppose we can all just carry a shovel or something in case…
