Somehow while manipulating our board, I broke all of our past sprints.
If I select any of the sprints other than the current one, I am unable to view any reports.
The main change that we made was around Won't Do status tickets, making them visible in the backlog and also in the rightmost column (which I just learned is how tickets are registered as complete).
The issues themselves are not gone, and they still have a sprint in the field.
Clicking on the sprint link takes us to an error page:
I'm not really sure how to go about resolving this.
