Loopbacks and Regeneration

Since 2003, Maestro had the concept of "Regeneration".  Regeneration for Maestro on Drupal 7 was a rather nebulous concept if you didn't understand the complexities that exist within the original engine.  Most administrators would simply check the regeneration option to "on" and the option to "recreate all in production tasks" and never worry about what it actually meant.  Simply put, as a human reading a workflow diagram, we can understand when a logic condition causes a loop-back over already executed tasks. However, for a machine to detect when we're looping-back over already executed tasks produces a set of logical issues that are not easily overcome.
