In the last 2 sprints, we are encounting an annoying situation with our scrum boards.
Let's say we want to close sprint 999 on "Red" scrum board which contains story A, B and C. Story A and B are completed but not story C. Once we end sprint 999, story C gets added to sprint 1 on a completely different board (let's call it "Blue board"). How can this happen?
I know in the documentation it is written incomplete stories could either be moved in the backlog or in the next plan sprint once we end sprints. But in our case, it does not a appear in the backlog (or next plan sprint) of expected board but on a different board.
Thanks for your help!
