Pandora got a 1 hour slot to perform in a UK con other than Vexpo(she confirmed it in a reply I didn't ss). She sent it pre-recorded due to possible connection issues. Then she learned they gave her slot to someone else and use a small segment(10 seconds) from her video instead.
This is a reply to someone saying many times cons tend to focus on numbers on spreadsheets and scramble around unaware. She allegedly didn't even get a corporate "we apologize for the mistake..." as an answer, but a literal

instead.
