You're probably playing the Patreon version. In this case, connect your Patreon account to Discord, join the game's discord and check the pinned messages in the Premium Announcement channel. You'll find the solution there :D
I just checked the code for the three premium version on the website and none is censured — the only way the Punish option could disappear is if a certain variable is turned on, and that variable is only turned on in the Patreon version. Are you sure you're not playing on a save created on a Patreon version? I can't really think of anything else that would explain it.
