Extend AFK to 15 Min / Keep Quests Activated After Logging Out

Hi, so I had to go out for a few mins then I come back, and the game kicked me out, as well as got rid of my quest, that I was currently on.
Is there a way to extend the AFK time, or maybe change it, where when you log out, your quest will still be activated, when you log back in? I just don't think it's fair that I'm paying 60 gold to do these quests, and they just get thrown away.
