I have been working on making a build in Minecraft Java Edition version 1.16.3. My build involves a large amount of Redstone lamps in an enclosed area that can be turned on and off. Recently, I noticed an error with the lighting in my structure, where even when the Redstone lamps were turned off, there would still be some areas with lighting present. I am not sure how to reproduce this issue, all I know is that it is a very distracting issue that ruins the build I am making.
