[ARCHIVED] Problems with Lighting in TS4

@elelunicy I was able to download your build and take a look in game, and I can confirm the dark cabinets glitch shows up in my game as well.  Another player also uploaded a test build, and in looking at both yours and hers, one thing I noticed that they have in common is multiple levels.  I found, while testing yours, that if I deleted a set of stairs (on any level), the cabinets were no longer darkened.  The other player had created an open story area, and deleting the stairs did not resolve her glitch, but drawing a complete room over the open area did.  Given the results of these tests, I think we're dealing with a problem in how light is flowing from one level to the other (or getting cut off), in ways that it shouldn't.  I can't be absolutely certain of the cause, because when I tried to recreate the issue by building a similar structure from scratch, it did not occur.  However, if you wouldn't mind leaving your test build up on the Gallery, I think a dev should be able to take it from here.  Let me tag @SimGuruNick, since he has already popped into thread once or twice.
