Unity Lighting Broken (Also I've noticed Clustering thing is failing... Related?)

Not sure if this is the right sub-forum, but whatever…

On a level I’ve been working I’ve been using the full bright thingy (lights the whole scene), but now full bright doesn’t work. Also I tried adding lights, and some things stay totally black no matter what. I tried manually baking, and auto bake, but nothing seems to work.

Any ideas?

Full bright?

Lower the precompute resolution significantly.

Was that the right term? I was referring to the little sun icon that lights the screen scene up even without lights.

Here are my settings (lighting) how do they seem right?
