Hi! There are indeed doppelgangers with wrong ID number, but because it is randomize and every character has at least 10 doppelgangers it has a low probability but don't let your guard down because the probability is not cero!
About the phone and the papers, it is that way because the phone cause a lot of bugs with the papers, so I decide to do it in that way.
I'm currently cooking the new game mode, I think it will be very interesting, and more horror focus.
Thank you for your help suggestion but because I code the neighbors in a so dumb way (and when I was doing it I knew it but did nothing about it because I'm also dumb) my code it's a mess and after the chinese incident I don't feel in a way to add more languages, so I'm sorry :c
