You can on the right here:

But not here on the left:

You can't use these stairs in symmetrical projects, like the above photos. You can't place the left-hand stairs against a wall, which in my opinion is where they logically might go. But what if...you could?

With a packaged version of these stairs, I tinkered around in S3PE until I managed to fix this oversight. The stairs are still fully functional, but can now be placed up against a wall!
You can fix this yourself...or use my already edited package: http://www.mediafire.com/download/x6tof ... 29.package
I really loved this set, but this minor bug drove me nuts and I couldn't use them when I wanted to. Now I use these all the time. I hope this helps someone!
