Thanks for the suggestions. I checked and none of those options are ticked (ie no Fog of War, Advanced Fog of War etc). However, I did stumble upon what is probably the issue and it looks like a bug. I started zooming out the map just in case I wasn't actually looking at the correct part and it became obvious that light is being emitted by my token but *behind* the map. Take a look. <a href="https://postimg.cc/RNd8L7RQ" rel="nofollow">https://postimg.cc/RNd8L7RQ</a> I have double-checked at the map is definitely on the map layer and the tokens on the token layer. The light is being obscured by the map itself.
