When I change the name of a puppet it loses its rigging - HELP

I am pretty sure the rule is if you change a layer name (which includes introducing an enclosing layer, or removing an enclosing layer) causes rigging to be lost from there down in the hierarchy. It treats it as a delete and add of layers - it thinks you deleted the old layers so loses the rigging.

For triggers the triggers still exist, but the bindings are to the old path names. You can look in the trigger panel and it should show the trigger and layer names in orange. You can drag the new layer names over onto the triggers to reconnect then.

If you change a puppet name (the name at the very top), well then it loses everything because it thinks you deleted everything and started a new puppet from scratch. Introducing walk profiles is almost as bad since they are right up at the top of the hierarchy as well.

Yes. Changing even the slightest naming will destroy your entire rig.

Not only that,

So one time I decided, in the middle of the animating process, to add a mobile phone into the hand of the puppet. So I opened up Illustrator and create a mobile phone and add it into the hand. Then I group the hand and the phone layer (without giving a name) and change the name of the group as "hand" and the formerly named hand layer is put to default as "path/shape". But you know what? A trigger for that hand is missing. The naming is exact, the hierarchy is exact. Only a new existence of group cause Ch to miss that hand. Hope you understand what I mean.

Did you ever figure out how to fix this issue?

Did you import the puppet again or just re-import its artwork file? Re-importing just the artwork (psd/ai) will not include all the rigging that the puppet file includes. There is some basic addition of behaviors and tagging of certain layers based on their names, but the control panel and triggers would not be recreated.
