Did you manage to bypass it in the end?
I can’t believe that there are two ways to reset the pins, both methods are described on forums, both are very vaguely worded, and the authors of both posts simply disappeared and do not appear for years after they found a workaround.
It feels like black magic surrounds resetting the offset of the puppet pins, and people who solve this riddle mysteriously disappear.
I feel like I’m going crazy soon.
Here is the other post I’m talking about. It uses resetting via a plugin https://community.adobe.com/t5/after-effects-discussions/create-puppet-pin-programmatically/m-p/7650169
