Ambrosia Software Web Board: Pynx Portcullis - Ambrosia Software Web Board

I'm stuck trying to get to the basement. I have found two loose stones and get a "click" from each, but the lever is nowhere to be found, no matter how many walls I walk through. From earlier hintsI found on this BB, it sounds like I should have found a lever somewhere in the "dark" area, but I've visited all of it to no avail.

Each time you step on a loose stone, some part of a wall is changed to a invisible secret passage. Step everywhere, then try to walk into every part of the wall. Eventually you'll find the lever.

If you have the "Romete Use" spell, you may go behind the portcullis without opening it: cast the spell on the stair, and voilà, you're downstair. Back with the "Directed Nexus"!

Well I had already discovered the walking through walls bit, and I have (I think) explored the entire space that shows as "black" on the magic mapping scroll (three rooms, three walk-thru walls). No lever. I'm baffled. I wonder if it's just missing from my database -- there
are a few other oddities here and there, possibly I have somehow
corrupted the db. I'll try the 'remote use' trick. Thanks.
