Original strings of code in the game files hold values that would have triggered Werewolves at certain days or even moon cycles. My guess is that they removed that option because you may fast-travel for 2 days worth and end up in the middle of a town with a full moon. Then again they didn't stop that from happening with blood-starved vampire.
