Hi there, recently I've downloaded Forge to play a multiplayer LAN modded survival with friends. Throughout the gameplay, I noticed that I am not effected by nighttime or areas with no lighting. I don't know what the cause of this could be. I have uninstalled and reinstalled Forge, I have tried other versions of 1.12.2 forge, going back to normal 1.12.2 everything works fine.
I've heard mention of the issue being caused by something like Optifine, but I have had this issue since before downloading such, and even after removing it. If I could relate this to anything, I would say it is like always having a "full brightness" hack on at all times.
Does anyone have any information on this issue or how to fix it?
