Ever since I made my new server spawn, there have been 2 areas containing extremely irritating lighting bugs: No matter what I do I cannot seem to get rid of them. I've had the random lighting updates option set to true in Spigot config for 3 weeks, so that is not the problem. The floor is lit completely with sea lanterns so a shadow should not be cast. I've confirmed it is not my client's fault 10 times over by having friends describe the same problem you see above. The dark spots disappear when you get close but reappear after re-logging. I have even gone so far as to consult sk89q, the creator of WorldEdit. He has no idea what is going on and ran many tests on it. Any help is greatly, greatly appreciated!
