It`s about this page here: Unity - Scripting API: Rigidbody.constraints
And here this RigidbodyConstraints.FreezeNone link is dead: http://docs.unity3d.com/Documentation/ScriptReference/RigidbodyConstraints.FreezeNone.html?from=Rigidbody
And i have the problem that Unity doesn`t know RigidbodyConstraints.FreezeNone at all. How do i unfreeze a constraint then?
