Here's the situation.
LBP is not saving my History progress. I have everything at 100% except The Wilderness, which is at 94%. Yesterday I grabbed what was missing via online play and I received the All Prizes trophy.
This morning, when I loaded the game, it was in the exact same state as before I caught everything. I grabbed all again. I went to play now and the same occurs.
I played some online levels and hearted some, and the game did not forget that progress.
I searched the internet and can't find a solution.
