Yesterday I bought the Embers of Rage DLC from GOG and installed it and it changed my UI theme in all my save games to the Dark UI which I don't like. I tried to set the UI Theme back to the one in the image above but it doesn't exist. The closest one is the Metal UI theme but it looks terrible in comparison.
My only Interface options are:
Dark
Metal
Stone
Simple
In addition, the main game menu is the dark UI and no matter what I do it doesn't change.
Is this all some kind of weird UI bug? How do I get the UI theme in the image above back?
