Static Batching on load level isn't working?

In the Editor I tried using OnLoadLevel() and it breakes my static batching, then when I assumed it was an Editor bug and in the webplayer or webGL it would work. But I just profiled a webplayer build and the static batching isn't working at all if the map isn't my main scene. Also tried to profile the webGL build but I couldn't make it work.

FYI, my static batching IS working when I play directly in the scene, the setup of the assets is right.

Is the Static Batching really broken if the level isn't my main scene? Is there a workaround?

Thanks!
