Missing config file "default_mp_controls.cfg" during initiliazation. May need to add to code_pre_gfx.I have Bo2 on steam and I was following this https://plutonium.pw/docs/repair/ I've verified my game files and moved my location of the game but still nothings worked. Much appreciated if anyone has another way I haven't tried yet.
