Volume absorption boosts light levels of scene and messes with shadows The first has a volume absorption node that is set to full white and 0 density for the water, it also has a glass BSDF set to white and an IOR of 1.33. The second image is the same, except the volume absorption node has been removed from the water material.


Here is my node set up:

I have tried recreating this effect in a simple scene with as few objects as possible, but I can't recreate it at all. (Additional information: I was having this same issue with a hair particle system in this scene, but that has since been removed from the scene.)
Why is the volume absorption node messing up my scene?
I raised the max volume light bounces to 64 and that has solved the issue
