Crouch Toggle won't work.

Crouch Toggle won’t work.
I typically have Crouch set to Toggle, but whenever I change it doesn’t change anything. If there is a way to fix this please let me know.
Important info:

  • Crouch Toggle has worked before and has only stopped working today. - Any other setting changes work fine. - I play on a keyboard and don’t use a controller.
    Thanks!

I am experiencing this issue as well.
The game refuses to acknowledge the Toggle crouch behavior.

I am also having this problem, but only for Reach and Halo 4. It really sucks for Reach as I mainly use Active Camo, and while crouch walking you’d stay invisible. Now it’s much harder to do this, and painful for the thumb.
