I accept defeat.
But here's some logic from the whiny little kid side of me who still wants his way (feel free to completely disregard this.)
If someone's order at a restaurant got messed up, would the restaurant decide it's not fair to fix it since some other customers decided to accept their losses?
Furthermore, I submit that it definitely was a client-side error, as opposed to server-side or a misclick.
Again, feel free to disregard this and move on with your day :)
