And just like yesterday, I can't boot the Vita version while connected to the internet. I don't know why, but the game only works when it's turned off.
Edit: I think I screwed up. I should've used deep vision at the beginning of the stratum, not the end. Now I know who the traitor is but my party are voting for innocent people. Is there any way to reverse this? Can I just continue even if I kill an innocent person, since for the true ending, I'll have to identify only the traitors, therefore getting the "all-seeing eye" trophy in any case?
