Top of some monastic quest towers is another staircase

[macksting]

In the Hwang Sa Temple quest line, sometimes the tower at the end is an endless tower. I haven't tested this since 1.100 or so, but I've got a tower in my latest 1.310 native save that goes at least to floor 11 or more reliably. As I recall, at least in earlier versions, I got to floor 30+ before I turned around and quit (for the fun of it, since I knew better.) Also I recollect finding it was a situation which could only be gotten out of if you saved before you went into the tower, and loaded from that save, so it seems to be between then and when the first floor spawns perhaps.
I have my current save game here.

I first encountered this problem on Windows XP, but have had it crop up with Linux versions as well.
