I'm sorry for this problem, there is a bug with cloud saves at present.
You may be able to recover your save with this process:
Short summary of your issue Ironman Game Progress Not Saving Game Version 1.0.2 What OS are you playing on? Windows What platform are you using? Windows Store Do you have mods enabled? No Have you tried verifying your game files...

IF you haven't subsequently started a new campaign.
Please only use local saves until this problem can be fixed.
My apologies for the problem!
