Update campaign history works as long as none of the contacts that were sent to in the campaign have not been deleted from the database.
For instance, it will download opens/clicks until it reaches a contact that is no longer in database. Once it hits a contact no longer in the database, instead of skipping it and continuing with downloading opens/clicks, it stops and move on to bounces. If it hits a contact in bounces that has been deleted from the database, it will stop doing bounces and go to opt outs. And so on and so forth.
