So I have previous maps that I've used the lighting on, with one way directional lighting, etc. for windows that are intended to be mirrored from the outside, but despite removing and putting them back in, they periodically just shift to become two way windows apparently. I'm guessing not by design, anyone else having this issue? It's intermittent. When I redo the lighting, it works initially, I leave that map go to another and come back and it's broken again. Thanks.
