We have noticed in the past week or so that a Task no longer seems to be able to live hierarchically underneath a Story. Previously we could add a Task or Sub-task to a story, now the only option is to add a Sub-task. We have not changed any configurations in the time since this has started.
A Task can still be created via the Create button, but it cannot be added as a child to a Story, no matter the method you try. Has anyone else noticed this behavior? I'd love to understand why this may have changed.
