Apparently a problem I reported was among issues that have prompted the Revit Structure team to post a new build just one month later. The issue I reported had to do with copy/paste tools applied to concrete beam families. I'm glad they figured it out!
You can download the BUILD HERE!
This is the list of comments in the pdf file found at Autodesk:
Improves API for beams creation with NewFamilyInstance (ref XYZ location,..)
Improves API for element coping.
Improves API for instance creation of cellular beam.
Improves API for rebar group distribution.
Improves File > Open performance time when opening some project files in Revit Structure software.
Allows the ability to array face-based families placed on a vertical face.
Allows the ability to maintain face-based instances on curved surfaces of a Revit file linked into Revit Structure when the link is unloaded.
Improves stability when selecting sections.
Improves stability when accessing the Help menu in Revit Structure on a computer with the Microsoft Windows Vista™ operating system.
Improves stability when applying a view template to a sheet.
Improves performance when views contain many objects with overridden graphics by element.
