Well just installed the mod, its really good no bugs on my part so far, but amazing job! But to get down to it, I pressed save, then quit the game to see if my bindings saved, and they didn't not sure if I did anything wrong? Or it just doesn't work. If you need my player log to fix it you can reach my at TheDuck#9258 on discord.
Load the game. Setup the bindings, Press save, close the game. Start the game, Press load on the mod UI, and nothing happens.
