Quality dependent lightmass light leak
As soon as production quality lightmaps are calculated Lightmass messes up one particular area by putting some weird light there:
Top is production quality with the unexplained yellow light leaking in. Bottom is the preview quality with the expected lighting.

Can you provide a little bit more information and perspective on your scene and setup for me?
When using Preview there will only be a single bounce of light used by lightmass whereas Production will use the number of bounces listed in the World Settings under the Lightmass section or what is set in the BaseLightmass.ini file if you set it there.
Let me know your asnwers to the questions above. I may have a few more after this, based on your answers.
