Issue Description:

Seems some facades do not light properly, and some have mostly black sides. Not really an issue but thought I'd make you aware (If you weren't already).
Breaking/ replacing the facades or conduits does not fix it.
These issues didn't seem to be present a few updates ago (Not sure which).
