Space Environment not lighting properly

Hi guys

Building a space environment and having some issues with my baked lighting.
Sometimes between certain meshes a light appears along the edge. I have played around with Shader Stripping options in graphics. There are both realtime lights and baked area lights + emissive materials in the scene. I don't have any directional lights outside, and my environment lighting source is set to colour, which is black (given that this is the interior to a spaceship only).

Note: All of my environmental assets (besides the doors) are static objects.

Lightmapper is set to progressive.
Have also tried baking without my realtime lights set to active.
Am yet to find a solution to this issue. Wasn't a problem before when the map was smaller.

Photos attached below show the problems (note that these areas are intentionally very dark as this is a survival horror game).

Would appreciate any assistance or advice!

Thanks

 

I start my project with a default example and lighting setup. Did you check if is a mesh problem?
