[FIXED] Stair rails disappear w/wall placement partially covering from the top

I tested both conditions reported in this thread and believe both things are caused by the same issue.  Whenever a wall or fence touches a stair railing either at the bottom newel post or somewhere along the downward slope of stairs, the railing entire railing disappears.  It does not happen where walls or fences touches the top newel post.  The wall can be parallel to the stair or perpendicular.  Tall fences like the GTW police station Be Prepared Secuity Fencing cause it too.  Both straight and bent stairs are affected.

Hope this helps.
