That happened to me, too. I was able to fix it by quitting the game and going back to the game screen in Origin and clicking Repair. Went back into the game, and it seems to be resolved!

What do you expect to see? The light doesn't appear
Have you installed any customization with the game, e.g. Custom Content or Mods? Never used.

This occurs every time I open the app and go on build mode. It started a couple of days ago, but I don't know why it is happening.
This is happening in my game as well and it even applies to fireplaces. Anything that gives off light will not show up when placed in build mode (even though the "placed" sound occurs) and there is no illumination of the space. All the lights in the existing houses are gone as well - both ones that came with the game/packs and the ones downloaded from the gallery.
