Hi @coregurlz
Sounds like b_ROOT_ bone has been moved accidently during your time in blender. Either that or the rig was first moved as an object in 'object mode' rather than 'pose mode'.
Best way to check for the second issue is to select any bone from either of your rigs in blender then switch to 'object mode' down on the lower toolbar of the 3D view window, then hit the keys alt R and alt G. If either hotkey moved the rig in any way then leave it where it has been moved to, and reposition it back to the location you want in 'pose mode' using the b_ROOT_bind_ bone.
The first problem is a little bit more complicated and requires you to go to the outliner and reveal hidden bones. Try the 'object mode' fix first, if that doesn't work drop me another message and we can go through the other fix.
