Completed daily tasks reappearing as overdue since 1st January 2000.
I have just ticked off a couple of tasks in the web app, both of which are set to occur "every day". Both tasks immediately re-appeared as being overdue since 5116 days ago (i.e. since 1st January 2000).
I have seen this happen once before, but at that time I simply ticked the items off again and they disappeared. This time, when I try ticking off the "5116 days overdue" tasks then they remain overdue.
