I have a giant room on a multiplayer creative server. The lighting in the room is so weird, there are dozens of patches of light from seemingly outside and light from like glowstone or something. I have updated to the walls and every block in the room using world edit, and I got nothing. If anyone knows any fix please let me know, it is driving me crazy. Feel free to ask any questions, for starters there is world edit on the server, and that is what I used to fill the ceiling. I have reloaded my game and then manually reloaded the chunks using F3 + a, and I have manually replaced the ceiling, but to no avail.
