Beacon Beam not showing

The beacon light (not light level) does not show up in the 13w38a. Changing the Post Processing option does nothing, Super Secret Settings should be on default, though I really can't tell for sure. I closed the game entirely just in case before checking the beacon again. This occurs in both singleplayer and multiplayer.

EDIT:

I should also mention that this occurs whether or not the beacon has been "activated".
