Lost aces challenge

Why have a challenge if you can not continue the game? The lost aces challenge takes me to the end of the game, but since you can not go any further past the last level because there are no more levels created. How do you play the challenge on a non completed level?


The icon takes you to the last non completed level. However you can manually scroll through the map to locate the other lost aces levels/games. It’s kind if cumbersome to do so but each region with the lost ace will have that “barrel” icon. Not just the final level.
