So I was on my adventure maps build server and was flying about with my elytra and noticed four bright patches of light on the ground. I swooped down to break what I thought was a torch causing it, but there was nothing there. Just light sitting out in the middle of the night.
I'm not sure if "anomaly" is the correct word for this, but I have never seen anything like this before. I've checked the world and there is no lighting, even way above the strange patches of light. I uploaded this world to my server.pro server without anything bad happening, and this is not anything of major concern to me, but I would like to know what cause's this and how to stop it. Research only comes up with people wanting to manipulate something like this (beep beep) without even knowing that it's possible.
