Components lost from detail view

I was working on a view all morning and after developing a rather complicated structure it magically disappeared. I don’t know what happened, but I “previewed as” a different User and everything was gone from the detail view.

I figured it was the User, so I “previewed as” myself and the components were still gone in the detail view.

Has anyone encountered this? Is there a way to recover it? I submitted a ticket but wasn’t sure if maybe I was missing something. I’m hoping I don’t have to recreate the view again and waste a couple hours.

Can we know more what component was that?
