I have been developing my game recently when I noticed this lighting bug between the walls, there are no lights besides my one sky light.

Looks like an intersection to me. Try not to overlap the walls.

Hi RazorBlade57 -

Take a look at the Lighting Troubleshooting guide, it looks like some small lightmap changes will correct the issue for you.
