it's a long time since we have this issue in Archicad. When we set stairs Floor Plan Display Layout in original file, these informations are lost after use these file as a hotlink. It would be nice bake the Floor Plan Display Layout when some file is hotlinked into another file or any other solution which would keep the original Floor Plan Display Layout of stairs.
When you create one project with a lots of hotlinks its really hard make one "clean" floor plan documentation. Using PMK or Views from original file is really painful and time consuming solution.
