Skylight not Updating

I adjusted the environment of my game to night time. It works- in the edit viewport, but not in the play mode.
What do I do?

Edit mode:

Play mode:

75309-screen+shot+2016-01-20+at+2.57.30+pm.png

Thanks.

Bump. Still need help.

Do you have the update Skylight only set in the Construction Script or also in the Event Graph?
Construction Script only fires when you create or modify the blueprint, if you want things to change in-game you will want to put that on the Event Graph.

How would I put it in the Event Graph?

Bump. Still looking for answer.
