Describe the solution you'd like

Publications themselves sometimes receive updates, normally this is just to text but can also contain bigger changes, such as an image change.

I have no idea how this is checked internally. We need to figure that out and then apply the same check on each download to make sure we currently have the latest version downloaded in Media.

Describe alternatives you've considered

Deleting cache and restarting.
