Hi, somehow this happened to me. Enviroment lacks lighting and textures, everything is dark. I do use a YAML mod, but it can't be it - I have been using YAML for over a year and this is the first time I am seeing this bug.
I did have VonBiomes mod, but gave it away, because it caused significant framerate drop. After uninstalling the VonBiomes mod, this bug occured. Then I did a fresh reinstall of the game and the bug is still there.
Can anyone advise?

Thank you.
