Not all light sources are baked


I have a level containing only a Skylight (set to Stationary with “Cast Shadows” disabled). Additionally, there are 36 Blueprints in the scene; each consists of a single wall mesh and two Point Lights. In total, there are 72 Point Lights, all set to Static. When I build the lighting, only some of the Blueprint lights bake correctly, while others turn out very dark. By the way, I do have a Lightmass Volume in the scene, scaled to cover the entire building.
