Lighting bug above y=95(ish)

While i was building in singleplayer, i noticed that after a while weird shadows started appearing, without anything above them to cast shadows

This all happened after i made a roof on a tower
After that, my character went to full darkness above that y coordinate
When i move away from the tower, it then pops back into light

When i exit from the world and relog into it, it first fixed the issue but after that it doesn't
