For some reason, it seems to me that the codes need to be redesigned. If the game uses four-digit input to turn on/off certain functions, then using three-digit codes can lead to errors and "bugs" like this one. Perhaps this is obvious only to me, as a person familiar with the concept of "don't do shit so that you don't get even more shit," but nevertheless, this is my feedback as a player to a developer. If you consider this attitude to work to be normal, then there are no questions - the dialogue will end exactly at this point.
