If you reload your save when the camera is in a certain area in the adamantine forge the game gets bright and desaturated.
Example Adamantine ForgeThis occurs only when the camera is in a certain area in the adamantine forge. (tested for the borders of this "area")
Area where this bug occursThis problem can be easily fixed if you move the camera out of this area.
The only problem here is during the fight against Grym when reloading the save, because I couldn't move the camera out of the fighting area to get rid of this problem.
