During the editing experience, what would cause the page template to suddenly change?
Suddenly in the middle of editing a page on the page builder, an editor got an error "Areas with the following identifiers are missing from the page markup: mainarea. Saving the page will result in lost data."
Generally I know this means an area identifier was changed in a view, however after looking into this it appears that the entire ContentItemCommonDataVisualBuilderTemplateConfiguration and ContentItemCommonDataVisualBuilderWidgets in the db were spontaneously changed to exactly match these fields for a page that was recently created. Since the content type of the page being edited at the time was of a different type, the widgets and areas obviously would not resolve.
The only way I can imagine something like this happening is making changes to the db directly. Any other insight would be appreciated.
