For some reason, whatever I attempt to do, this map seems to be pitch black for my players. I've tried activating fog of war, revealing the entire map, then resetting the FoW. Deleted the dynamic lighting entirely. Created an entirely new campaign with the module. Nothing seems to help, and it seems to be the only map that has the issue in the entire module. Possibly a bug? I don't know, but at this point I'm submitting the bug report. I've DM'd the module several times before, without issue, so it's something new that's happening. I'm using Windows 7 pro, 64 bit, with Google Chrome version 55.0.2883.87 and Flash version 24.0.-1. I've had one of my friends attempt to look at the map with Firefox version 50.1.0 as well, seeing the same thing.
