I'm trying to make dynamic lighting work for my campaign but after painstakingly outlining and setting up things like darkness spells, I have found that various parts of my map have seemingly random walls in the lighting. These aren't mistaken auras or forgotten walls that need deleting. They are not select-able and never did I even attempt to make a wall where they have appeared, or if I did it by mistake while using the polygon tool, I always made sure to ctrl+z or delete the problem wall. I have made a gif to show one such wall that is a hook shaped box in a cave with some stalagmites. <a href="https://i.imgur.com/6uG6Cjl.gifv" rel="nofollow">https://i.imgur.com/6uG6Cjl.gifv</a> I wish I could figure this out and hopefully this is a simple misunderstanding of the system, but I swear I've tried everything.
