NLA editor "not working" properly

When I add a new animation strip ( a walk cycle) my rig jumps to a random location and is also scaled up. What am I doing wrong?

I guess there are 2 possibilities :

  • The armature itself is animated (in Object mode) and has a location keyframed
  • The bones are keyframed far from the armature’s origin

Sounds reasonable.

Also, I’m worried by seeing your main controller war away from the object’s origin. Without anything that seems to justify it.
This should be centered. Pretty much always.
