This is true, I think im going to wait until I build my new PC before trying to get back into the game. I will more than likely not enounter any issues at that point.
I have been using these mods for years, they have never ever caused a problem like this. They are not the problem. I think its more likely a new update broke the lighting.
During the night my lighting look like this. Playing with graphics settings related to shadows can change this effect but doesnt fix it.
I am using some mods but none of them are related to graphics in any way. I only have zombie spawning increases, custom cave generation mod and custom POI packs.
