Most light sources do give off shadows, but some don't, such as the lantern or candles. This is probably because in real life these kinds of light sources give off very blurry shadows which could be hard to render properly in a video game. In my opinion the no-shadows technique from these light sources is better than having all light sources give off precise shadows. It would be much more noticeably flawed if they chose the latter option.
