Russ, that has happened to me more than once, for sure.
Whenever I do a service, or a simple panel change, I simply identify all of the existing circuits, and tape together any double pole cb's, before removing any of them from the panel. Other than that, the only branch circuits I will examine are the ones that may or may not be terminated in boxes near the panel that violate the code.
