The special ticket for the compulsory refund of flying pig double 11 "flew away"

In the early morning of November 11, Mr. Chen of Hangzhou robbed two special tickets from Shanghai to Tokyo on the flying pig, and the two returned 2664 yuan. Originally, I thought I picked up a leak with joy, but when I woke up, the seller said that the ticket failed. The flying pig platform said that it was because of the batch problem of the system. What the hell is going on?
