There is a secret in this game with very "specific" requirements. So first you need to go to custom night. Type in DETREVNi's name three times (you must have everyone else at zero). after that start the night and instantly close the game in under two seconds and reopen it. Go to %appdata% and there should be a file with tres data. You then need to find DETREVNi's AI level and set it to 1996. After that start the night and close the door quickly and then wait until you go to sleep. If done right DETREVNi will crash your game and you will unlock green DETREVNi. Only one person has unlocked green DETREVNi so far and they go by the name "Combinnmimebut" unfortuantely their account is gone. I don't suggest trying to do this challenge.
