For anyone interested, there is a work-around for the sprint problem, however its still bugged as hell. But this at least makes it so you can run without having to hold the button down:

Unbind all keys from all “sprint” movement tabs.

Go to “sprint” and set it to your “walk forward” button.

You wont be able to walk/jog at a normal pace without running/draining stam, but at least you wont need to hold the sprint button down. Its the best temp-fix we have found on my testing server.

Also, if youre an admin and wondering if this bug effects your fly speed… it does.

Hope that helps some people even a little. Def not a fix but its at least a “get by” for now.
