Pretty much exactly as it says in the title, on the Ruins of Thundertree map in LMoP my players entered in the day. I put blocks on the buildings to get lines of sight etc, but none of that happened when I put the global illumination on. This is starting to get really quite frustrating to the point where I'd be tempted to just leave out the dynamic lighting altogether and stop paying for my subscription. I got it working really well on some maps I put my own DL on, but this paid version, not so much.
