Duplicating a Site in January 2021 - Process Changed?

Hello!

Since 1/7/21, when I duplicate a site in our account, the element ID's in the pages change from those in the original site. This makes any custom CSS in the site invalid.

There is also a series of new dialogs to step through when duplicating the site - "What would you like to call your new site?" etc.

Has the Duplicate Site process changed, or has something changed in our account that makes the process different in 2021?

Thanks for any help/advice!
