Hi,
I built an enderman head and had the idea to have the eyes glow with redstone lamps in a sequence. But a random light source bug ruines the way it should work. it is supposed to go complete dark for a couple seconds but the left side of the face stays lit with an invisible light source. Even the redstone lamp sequence in a different location causes it to have random spots of invisible light. I have looked up on how to fix this but there doesn't seem to be a solution.
