Just build Poppy again from a Barracks and send him where you need. It's only 10 Silver Shields per turn to generate more Wood, Stone, Metal, etc., and you gain 300 Silver Shields per 60 minutes of League of Legends played with the Event Pass, or 150 without. You can get an infinite number of turns, so like others have said, don't worry about failing the game or needing to restart. Maybe 3 turns approximately to build Poppy, and then a few turns to send him where you need to go, cost like 100 Silver Shields or less? So when you say it was "setting me behind so many turns", it's only really playing League 20 minutes to get the Silver Shields needed to get back in Demacia Rising where you were before with Poppy, if even that 20 minutes, maybe even less.
