Switching Fire and Alt Fire messes up your spectre and main body

Kind of a weird bug and I pretty sure you guys didn't account for it. I switch my fire and alt fire button around when I play fps game. So my fire is my right and alt fire is left. When you do that your spectre and main character gets mess up. Hopefully you guys can fix it lol I know there probably only a handful of people who switch the fire and alt fire mouse button.
