We updated a required custom field, replacing it with a select menu which is required. All has been fine with new issues.
We added sub-tasks to the project, something we didn't need previously due to the nature of the work. But one issue in the project is better served with sub-tasks.
While creating a sub-task (in an existing issue), we get "Original custom field is required" and it indicates that the original custom field is needed.
I can't find anything in the config that says the old field is needed anywhere. How can I get the sub-tasks to
* ignore the missing original field
* ignore the new field (it's included in the parent task, so redundant in the sub-tasks)
