BUG: Crash on 4.16 master branch, enable forward shading, disable "support stationary skylight" open mesh editor with default world grid material

BUG: Crash on master branch, to recreate.

Using the latest 4.16 master branch build:

1.) create a new project.
2.) Import an .fbx static mesh and don’t import material (so it gets assigned the default world grid material) from the file menu choose save all.
3.) in project settings, enable “forward shading” and disable “support stationary skylight”
4.) restart project
5.) attempt to open mesh from step 2 in the static mesh editor. You should get the following error.
