I'm having trouble with this mod, even though it is leagues above Atmos in quality and... working...ness.

When Stormfox is enabled the map is does not change light, if it goes night to day or day to night, if clouds clear or form the map still retains the same level of light, although on maps like GM_Boreas the 2D grass things sometimes changes colour.

UNLESS a TFA gun is fired, a rocket explodes or a Simfphys sports car's exhaust blows, then an ugly square appears that is the light level the map is supposed to be.

I've disabled all my addons and tried it on GM_Construct where it has worked properly, but I also tried it on a mod map and the glitch continued on it, the thing is though is that this map used to work perfectly fine, meaning it can't be a mod confliction. This happened after I completely wiped Gmod off my harddrive and then reinstalled it.
How do I fix this?
