I've noticed light intensities are having a more potent effect than they should.
E.G when trying to help people farm empyrean feet, I'm seeing HQ temps and NM KIs in golden pyxides at only 128 amber light.
I shall assume this is a bug because there's no incentive to build lights above 50% if you get the best pyxides anyway...
