I don't remember putting it there but that lantern must have a photocell.
Thanks for the GI fix in the latest update. I always wanted to do this but I was just getting a completely RED render with the previous version
It needs a few final adjustments but I am so pleased that is now working I decided to post it anyway.
The foreground grass is definitely a problem; I am sure I read that there was I fix for object placement in this latest update, I will have to investigate further.
