Hitman: Absolution level didn't save

As the title says, my level didn’t save. I know it technically did save since i moved on to the next level and I saw the little save symbol, but I just booted my xbox up and I’m back where I was. Normally I would be too upset about this but I’ve worked for weeks on this. Is there any way I can get the save back or any cheat to skip the level. I really don’t want to do the whole thing again. Thanks!

Absolution has manual save locations in each level. Use THOSE to save; don’t rely on autosave.
