I'm using Forum_Account's Dynamic Lighting library to help simulate day and night. However, it seems to be creating some issues with opaque turfs.
I've gone through the library but can't find the source of the problem. Any help would be greatly appreciated.
You also might want to check out FIREKing's own improvements to the library here, which speeds things up and solves other problems. I forget whether or not it solves this specific problem, but I'm pretty sure the solution above can be applied if not.
