Try and avoid using passwords in your comments please, it ruins the experience for others only just discovering the game.
On Day 10, Sal will let you pass that scenario regardless of if you get the password correct or not.
As far as CGs vanishing, what are you referring to? As in from the gallery or?
I remember there being reports of certain CGs not unlocking immediately after seeing them, notably with ones tied to passwords but there's never been a known reason for this to be happening.
Made worse by the fact the testing build normally shows everything working fine. Presumably it has something to do with persistent data but beyond that, I wouldn't have a clue.
