so.... there needs to be a way to search for or report on ghost-assigned tasks.
I know I have many, as they crop up on occasion, but now I can't find them!
I would be fine with a filter, report, export... anything that keeps the assignments intact for Deleted Users.
Ideally, it would be a filtering choice that gives me a live list (versus an export) that I can mass-edit, although often it's more of a slow, deliberate process of deciding who now gets the task assignment, so I'd prefer to have more options than only the 'sledge hammer' of Mass Reassignment.
Lastly, as an Admin, I should also be able to view a list of Deleted Users in User Management Tools.
