In a field set I've changed an asset container from one s3 bucket to another, I've manually updated the paths in the markdown files to the new image locations. But when I visit the admin for the page all the image fields are empty and when I update my content Statamic thinks that the image fields are empty so removes all images.

Is there a way to tell Statamic that the fields aren't empty and to use the new url?

This feels like a bug, but asking here before raising a ticket.

Thanks
