I had this problem too. What I did was delete the windows and check to see if the cabinets are lit better. When they are fixed, I put back the windows.
For those with the darkened cabinet issue, are you working with a single or multi-level home? In the two examples I was able to test, it seemed to have to do with multiple levels, and in one case, an open story area. I have yet to be able to reproduce the bug in my game, so I am still looking for additional test cases. If you can share your bugged build on the Gallery (call it "Test Cabinet Bug" or the like), please let me know either in this thread or the Build Mode Feedback thread.
this is a single level house with the lighting problem. I enclosed the kitchen with a temporary wall. knock out this panel first and the light stays on. (it doesn't face a window directly)
Then you can knock out the other panels and the light stays normal.
@Marjia what happens when you re-load though? Sometimes it seems like you can work around the cabinets darkening, but when you re-load, they'll be dark again...
