Can't get rough reflections working again, how to fix?

Here’s an old version of the same project, from before I changed something that broke the lighting:

and after:

it’s the same level. I just migrated the level and everything on it to the new (broken) version of the project. same lighting, same materials, same level, same everything.

What could it be that is different from one project to another?

I checked the world settings from both, they seem to be identical. trying to see if in project settings there’s something different, but i have no idea what could it be. ideas?
