I've ran into the problem as of two patches ago that indoor lighting chandeliers don't work. I see them on the ceiling, but they emit zero light. As if they're not there. The fireplace still works, but its the only source of light in an otherwise well-lit room. I changed my graphics multiple times, messed with my NVIDIA control panel settings, reset everything, checked drivers. Even lanterns don't work. I bought a lantern and it did not give off light as it used to. However, when I switch to an alt and switch back, the lantern works. When I visit the house I was just in, the lantern stops working, and the chandeliers are still dark. I noticed in a recent patch note that this was a problem that was fixed. My friend noticed it happened to him only in Velia residences, but my problem extends to all indoor residences, including my own.
