Games like MAG, Dante's Inferno, Bad Company 2, RDR, Skate 3, Dragon Age, and Borderlands all may have problems. I'm not sure exactly when RX fixed it, but it's been several months.
Is that it? I couldn't figure it out. All I had to go on was that when Liars and Cheats trophies got added for RDR it was working without me deleting the list, but when Undead Nightmare trophies got added, my secret trophies from the original list got messed up. At that point I just figured it was because of new secret trophies.
