Skeleton2d totally collapsed after reparenting

Question

I have a complex Skeleton2D set up with a number of polygons.

After accidentally reparenting the AnimationPlayer associated with this Skeleton2D, it has collapsed all the bones and polygons to a single tiny point, as seen here:

However, as soon as an animation is played in-game, the skeleton assembles and the polygons display correctly:

The skeleton doesn’t fix itself by just playing an animation in the editor, though.

Is this a known issue? Is there any way to fix this and un-collapse the bones? I wouldn’t even mind having to manually replace them, but since I can’t see the polygons in the editor that’s impossible.
