Note here: The reason some of these updates require a new save is due to multiple factors such as
game breaking bugs that can't be fixed on a existing file.
A ton of new content that you might not see unless you start a new game.
or you activated a little trigger during the dev scenes that might make you lose your save file (I'm looking at you cheaters.)
Also I don't mind cheaters, it was a one-time joke in the system for those who cheated to defeated the unkillable boss. you would not encounter this outside of that specific line of code.
