I recently created a copy of a form in a business process and updated the process to use the copy. I was under the impression that the copy operation creates an exact copy of the form utilizing all the same fields and maintains your field/lookup rules. I didn't notice until a few days later that our business process kept having suspended tasks, after researching it a bit, it turns out that the field rules action was reset to "Ignore when hidden" for every single one, causing some important fields used in routing to be blank. 

Has anyone else experienced this issue? Is this how the copy operation is supposed to work? 

We are running Version 10.4.0.1256
