Since several days ago my cloud saves didn't working and still remained on several hours ago save, and so does the stats on ubi connect.
and I can't complete time-limited challenges since a few weeks. I already assassinated a lot of enemies and it still say I killed 0 person, won many drinking games and still got 0 contribution. Last week challenges was the same issue.
Really need help from you guts.
