I wouldn't count on anything getting fixed for C1, especially obscure features like the layout object. If the layout object works for you then that's great; personally I haven't tried it in a long time so I have to experiment with it again to see what's buggy/broken about it. If it works with the mouse and keyboard object my geuss would be it's something wrong with the input system plugin. The layout object has random bugs/incompatibilities like this, which is why people say it's buggy. If you can get it working then you're set.. until the next bug comes along and you say screw the layout object
. I guess it has its uses but I don't find it terribly necessary. I wouldn't rely on it.
