error, error, error in the latest autopipe

The feature that used to be copying branches in a header line is gone in your latest version, please return the old programmers that's applied for both STAAD and autopipe every update you make problems for us, now I have a project very urgent and I had the model started in ver 12.00.00.14 and I spent a lot of time in it, until today when I upgraded to the latest ver 12.01.00.09 and did some changes until I wanted to do copy branches when I discovered an error in the software which think the base point out of the selected  range (which is at the header) and I was able to copy it in the older version. the issue is I can't open the model anymore an older version even (12.00.00.14) as it says is not compatible. What are you doing Bentley, why you release untested update especially when non compatible with the older one.
