Can anyone help? I have 100% completion on Lego Batman on the PS3. I have completed all hero and villain missions, collected every power brick and canister, rescued all hostages, completed Wayne Manor and Arkham Asylum, bought every character and every other upgrade, extra and data I can but I have one last data that's still locked. My save file says 100% complete but it still wont unlock and let me buy it. Any clues or is it a glitch?
