Is there a problem with plan regions and stairs that are attached to a lower level? I have a stair that comes to a mezzanine type landing, and the stairs down to the landing display properly. The stairs up to the landing don't show up unless I change my view range. I can't change the range for the entire plan, so I tried to add a Plan Region with the appropriate (I think) settings, but the stair doesn't appear.
Is this a bug, or am I doing something wrong?
