Animation with "child of" constraint not working

[bandages]

@acisre

The problem is that after the disabling of the child of constraint, the plate allways jumps back to its original location.

I didn’t look at the file.

From fresh, with no keyframes: jump to last frame of child-of influence. Keyframe transform and constraint influence. Advance one frame. Apply visual transform (ctrl a in 3D object mode for me.) It’ll jump-- that’s okay. Set child-of influence to 0. Now it jumps back. Keyframe transform and constraint influence.
