[Steuard]

There were easily visible stairs in my level 1 and level 3, but on level 2 I walked around the whole map twice without finding them. Possibly I was just being oblivious, but I eventually tried moving sideways onto what I thought was a slightly odd looking wall segment (I wish I remembered what exactly made me think it looked odd), and suddenly I was on the next level.

I don't know whether somehow the stairs icon just blended in with the walls unexpectedly well and I managed to not recognize it in that context (which seems possible but hard for me to believe, given how much time I spent walking in circles looking for stairs), or whether something odd was going on with the icon being different or distorted for some reason.
