I have an archive project where tasks are moved as they are completed. I was doing some analysis today and discovered that the task is essentially recreated, erasing the original create and completed date, but doesn't change the status which just furthers the confusion because now it shows hundreds of tasks marked completed, but with no completed datetime.
That means I've lost a lot of historical data which was the purpose of requesting the created/completed datetimes in the first place years ago. A task being moved to a different project shouldn't erase that history. It should just update the modified date.
Between this and not being able to export the data to a csv in the first place, something that is provided by a competitor I'm researching, it may be what drives me to switch.
