So Panzer and I have both so far suffered multiple times from the "Hey, why is the game starting me over from the beginning again??!" bug with Blacklist.
Apparently Ubi decided that the cloud-based version of your save is the master, and it periodically gets wiped out or corrupted, so if you have "sync with cloud" checked the perfectly working, multiple parts of the game completed local save will get overwritten by an EMPTY save from the cloud that makes you start all over again.
Thanks to Win 7's recovery feature, I found older copies of my 4 save files and then disabled the cloud sync, allowing me to recover where in the game I was...NO thanks to Ubi! I will NOT be reenabling it.
