Fullmoon night forever

I chose the game settings in Night Only and Winter Only, when the fullmoon night came, the fullmoon effect wouldn't show up if I stay awake at the moment.

But if I sleep through the day, the fullmoon effect would appear as normal, step up from cave or reenter the game would do the trick too.

And if I keep surviving when the fullmoon effect turned on without entering cave, sleeping or quitting game, the fullmoon effect would last forever.

I havn't tested the other DLCs yet, but I thought the fullmoon bug would be the same in Night Only mode too.
