As the video shows I've put a null object to move the head more easily, at first it worked, but now doesn't. The only thing I did before "breaking" it was adding the ik of the wings and moving the mesh for the body inside a large folder for the whole 3d model. I tried already removing it and adding it back in, or adding an anchor, but none worked. Does anybody know why it's doing this? And is there a way to fix it? I done it on mobile, so I don't know if that's the problem
