User blog:GothLoliManda/Bioshock Infinite-Checkpoint Issues

Is anyone else having issues where, between the Finkton Proper level, and (at least) to Emporia, there are no checkpoints? This would be my second playthrough, if the game would save, but it's not saving. I've gone through the whole Vox-turning-against-me thing 4 times now. I'm pretty frustrated, because I can't just leave my XBox on all the time. (It's already starting to smell slightly like melting plastic, the thing's old.) Is there a way to force a save, or is it only Autosave?
