I can reproduce the problem that was reported here:

When you delete a Puppet environment, any provisioning templates associated with the environment are automatically deleted.

Steps to reproduce:

1. Create a new provisioning template
  2. Associate the template with a Puppet environment
  3. Delete the puppet environment

After this is completed, the provisioning template is also deleted. This creates an entry in the audit log similar to:
