Rigify Rig moves twice as fast as the Armature Root bone after parenting everything to the Root i'm working with a rig that i will be using in Unreal Engine 4, and to avoid compatibility issues, i have parented to the Root bone everything that was not parented to it, but this makes the Rig move twice as fast in any direction than the Root bone.
I guess it's a problem with the root affecting the Rig twice through the bones i reparented, but i have no idea how to fix it.
Here's a gif showing the problem:

Here's the hierarchy:

The hierarchy is not fully open because it wouldn't fit here, but just know that the groups starting with MCH are the ones i parented to the Root
It looks like you might have two armature nodes where you only want one. Look into this possibility. In my experience, double transformation weirdness can often be traced to having an extra armature node that was created accidentally. This often happens by the old armature node not being deleted before trying to rebind a mesh. An armature node will be created every time you try to bind a mesh, even if that mesh already has an armature node attached to it.
