Frustration of lighting

Hello,

I have a project that has several scenes, the scene I a having trouble with gets loaded as an additive scene. It has its own camera, and the main scene has its own Main camera. The loaded scene has one directional light. Initially when playing the loaded scene after being added to the main scene, the lighting was "darker" than it was when loaded on its own. I got from the forums that I should disable the auto light maps on the scene and bake a manual one. That worked. The scene now loads as an additive scene and the light is correct when running in the game window. So far so good. However, the forums indicated that the problem would not appear once the game was built! Well I would be so lucky. When I build the game for standalone or for WebGL the darken light problem is back! I have the quality settings set to fantastic. I have tried with Shader Stripping lighting modes in automatic and in manual. I am out of ideas. What does it take to make it work on the actual builds? What else can I try?

thanks
