Oh haha, I guess it's due to the fact that relight does not use color correction at all so maybe the game is freaking out that it's not loading any. Originally I had my own color correction files that basically zero'd out all the parameters, but I just basically told the env.xml to not load one to save on mod download size. I think it's harmless even if slightly annoying to get a warning. I'm going to reframe from updating it until the next notable version release.
