Lighting on level restart

Hi,

When running my game on a mobile preview I have a problem when the level resets.
I’m resetting the game by reloading the level in blueprints.

I’m using one dynamic directional light which works fine on the first playthrough, but when I die, and the level reloads, everything is black, no light?

Do I need to be doing something to recompute the light on my resetting function or is this related to some of the issues of seen others having with mobile lighting?

Thanks in advance

Seems fixed in 4.7!

Thanks
