sociallubricant: So I've made it to Level 5 of the Catacombs, and I can't seem to progress any further. All other avenues of the map are dead ends. Solid walls with no interactable objects/doors. As you can see in the image, there's explorable space beyond this area here, with a chest where my cursor is pointed. But there doesn't seem to be any means beyond this point. I'm a warrior with no magic investment, so I can't use a phasing scroll either.

I don't remember this ever happening way back in the day, though I could imagine it being a problem.

sociallubricant: Unfortunately, the stairs leading down from Level 4 and the passage to Tristram are right next to each other in this instance (the screenshot just barely cuts off the second set of stairs).

Realpsojed: No, the game shouldn't create maps with impassable walls. It's my first time seeing this too :)
