I just tried turning off my internet, played 2 rounds of Wish Fountain (found 2 horns for banishing!!), closed the game, restarted the game, reconnected to the internet, and my game had saved everything - no loss of experience, items, progress on the quest. So it looks like you are good to go, as long as you can make the connection before the quest ends in 9 days.
