So I beat Uncharted 3 the other day, and right when I reached the final cutscene, the system froze. When I turned it back on, 5 trophies that I got - 30 G-mal kills, 30 M9 kills, 30 tau sniper kills, charted easy, and charted normal - all disappeared, and now everytime I redo the final chapter and beat the game again, those trophies do not unlock! Even though I beat the game, the charted easy and charted normal trophies won't unlock?!!! How is that possible?! Someone please help.
