My Project in 5.0 has no Problems.
But Changed 5.1 , LightProbes color changed to Gamma Space.
It was Baked in Linear Color space and before LoadLevel It work correctly. But after LoadlLevel It changed Gamma Space Color.( Brighter than before).
May be 5.2 should have more Problems.
I know this isn’t “proper” solution, but please rebake them into gamma color space. Linear color is outdated system anyway.
