I'm not sure how I do that, but basically the simplest way I can word this is when the cross hair is plugged into my Xbox the b button on the Xbox controller (crouch/prone button) won't work, and any button I have mapped to B (crouch/prone) doesn't work. Like if I don't have the cross hair plugged in and I hold B I will lay down, but with the cross hair plugged in if I hold B nothing will happen, the cross hair just isn't registering the press, it only became a problem the other day which is what led me to believe maybe my mouse button broke but it's still fully functioning, I don't know what's wrong with the cross hair
