So my map originally was dark and the sun was disabled so everything was pitch black except the lights around in it. All of a sudden since the game updated, there is a blue like sun or maybe just a lighting glitch in my map in which even when the sun in my ssi is disabled, my map is lit up blue. Ive tried everything and cant figure it out. I copy and pasted my map into a new mod and at first even in radiant it was fine and dark like before but then i compiled it and now even in the new mod its lit up blue. Any ideas on what is causing this?

EDIT: While trying to make my new mod to paste my map into, the new map window wouldnt let me type in anything. I wasnt allowed the name the map anything other than numbers at first
